Subject: Any model Hamiltonian of polyene(C4H6,C6H8,C8H10)?


Dear CCLers,

  I'm interested in the photoisomerization dynamics of polyenes.
Does anyone know the literature concerning the model potential of
those and parametrization?
  Any hints or comments concerning this subject are 
welcomed. I will post the summary of the responses if there
would be any.

**************  * Postdoctoral Position *  **************

EC project: 

Human Capital and Mobility on High Temperature Corrosion Testing

Location : Toulouse - France
Salary : about 12000 FF. after charges and social security.
This position is available now and for a duration of 12 or 16 months
Contact : Daniel Monceau
          ENSCT URA 445 CNRS

          e-mail: MONCEAU@CICT.FR


Candidate:
           The candidate must have a European community nationality (but not
French). He/she should know about one or several of the following analysis 
techniques: SEM/EDAX, XRD, TEM, metallography, thermogravimetry. 
The candidate does not need to be specialised in high temperature corrosion, 
the position is opened to PhD in metallurgy, chemistry, physics, materials 
science. French speaking is welcomed but not compulsory. Toulouse, the 
"pink city", is a very nice place in the French south-west with a lot of 
motivations to learn fast some basics of French language !


Subject:
	The work in Toulouse with Prof. Bernard Pieraggi concerns the role of
interfaces in high temperature corrosion. This project is conducted as well on
model materials and on superalloys used mainly for aeronautics applications 
(Toulouse is a centre for Space and Aeronautics Industries). The current study
is the interfacial effects of reactive elements (REE) on the growth of oxide
scales. It has been shown that Ca or Sr could retard the growth of NiO on nickel.
The postdoc will conduce more experiments on this topic in order to clarify the
role of these additions and will work on the modelisation of this phenomenon.

Dear Colleagues;

     I am working with a Sybyl .mol2 file under DOS (file extension ".mol")
which consists of a set of _disembodied_ (i.e., non-bonded) atoms floating in
space.  So far I have been unable to visualise this file using PCModel for
Windows, HyperChem for Windows, or MOL2MOL for Windows, but I have succeeded
in visualising it with RasMol 2.4 for Windows.  I wish to obtain a stereo-
scopic picture of this arrangement of atoms in space, but RasMol 2.4 only al-
lows you to export in a limited number of _non-chemical_ formats such as
 ..bmp and .gif.  Therefore, does anyone know of a mechanism whereby I might
convert a .bmp or .gif image into one that can be visualised by PCModel,
HyperChem, or MOL2MOL so that I can use one of these programmes to generate
(and print) a stereoscopic image of this set of disembodied atoms?  I might
add that Babel for DOS rejects this .mol file consisting of disembodied
atoms.

     Thanks in advance to all responders.


Sincerely,

S. Shapiro

Dear Netter,
            I am looking for some programs(for IBM PC) for geometry 
optimization of  metallocomplexes with 'sigma' and 'pi' bonds:

            - [Me-CH=CHR(Hal)n]  Hal=Cl,I; Me= platinum group metal
              (sigma vinyl complexes.)
            - [Me- - - C=C-C=C(Hal)n] ( pi complexes of platinum group 
              metals with  substituted dienes).

            Also I will be thankful to you if you let me know the 
references that contain X-ray data and Quantum chemistry results for  
complexes of that kind.

Many thanks in advance.

Hallo netters,

I investigated the document about MO visualizers and found a lack
of electronic structure viewers. Most often just the molecular
structures were visualized.
The few suitable programs were used on specific hardware platforms
thus PC's-based programs were scarce.
In connection to MS-Windows-based text-processing I'm looking
for a program generating electronic density graphics from G9x-output. 
It shall be great to have isosurfaces for planes through a molecules.
Anybody, who has found or writen programs doing this, should be free to mail
me about their experience. I'll summaries on the net.

Subject: Re:Semi-empirical programs for teaching


Below is a summary of responses I received in answer to my request for
advice on free or low cost semi-empirical programs for teaching purposes so
that students might have copies for their own computers. Information is in
the order recieved. My thanks, and that of my colleagues to all
respondents. One of my coleagues has ended up using MOPAC, another GAMES,
and several SPARTAN (currently on SGI, but the Mac version is awaited).

1.I don't know if this is what you are looking for, but we are about to
release MacSpartan for the PowerMac platforms.  Currently, you can acquire
information from our WEB site at http://www.wavefun.com.

MacSpartan is due to be released during the first quarter of 1996.
MacSpartan includes:

1. A Graphical User Interface, much like Spartan for UNIX systems, that
includes BUILDERS for:

A. Organic Molecules
B. Polypeptides
C. Transition States

2. Calculations using the following methodologies:

A. Molecular Mechanics (SYBYL)
B. Semi-Empirical (AM1)
C. Ab Initio Hartree-Fock (3-21G and 6-31G* basis sets)

3. Displays:

A. Structure
B. Molecular Orbitals, electron densities, electrostatic potentials C. Animation


MacSpartan will run on all PowerMac platforms with 16MB of RAM, preferably
with a 66MHZ processor or faster. All appropriate screens are supported,
but the minimum for practical use is 13" and ideal is 16"/17" or greater.
Obviously, the faster the machine, the better the performance--and your
8500 will more than do the job.

And...the academic price for MacSpartan is only $299!

If you have any further questions or are interested in acquiring
MacSpartan, please get in touch with me at the address below.

Thanks for your interest.

2. MNDO source code is available from the QCPE at Indiana University.  Also, it
is not semi-empirical, but I have a nice little version of an ordinary
Huckel (that is, pi systems only; energies in units of beta) program,
including parameters for heteroatoms, and an instruction manual.  I'd be
happy to make it available, free of course, on my ftp site.

3. I have two Macintosh HMO programs:

1) HMO written by Harry Haddon and John Farrell at Franklin and Marshall
College in Lancaster, PA. It is quite old now: 1985 version. I don not know
if it has been updated. A so-so program.

2) HMO written by Allan Wissner, Oncology and Immunology Section, Medical
Research Division, American Cyanamide Co., Lederle Labs, Pearl River, NY
10965. This program would be nicely suited to Chemistry seniors. It
displays the MOs graphically, which can be copied and included in text,
etc. It also has an implementation of the "omega" technique. This one was
*free* at the time!!!

I searched the net for HMO (got many Health Management Orgs. hits) and
Huckel + HMO and got no hits. Apparently these programs are not supported
on the net.

Hope this helps! GN

5. Jack, MOPAC for DOS is very good. The only thing I'm not happy about is it
doesn't have a graphical interface to create Input with. You have to literally
type in the numbers describing the geometry in order to create an Input, whihc
is very prone to error. I've never done this. Fortunately my advisor spent ca.
$1000 buying CAChe package including MOPAC and its Editor. The latter is a
chemistry-informed drawing program. I can use it to create a correct MOPAC
Input for any platform including DOS.

I have a feeling that somewhere on the Internet there's a program we can use in
place of my CAChe Editor. Somebosy suggested SYBIL but the free version can
only accept 10 (?) atoms which is too small for me. If you get a response about
such a program, please let me know. Thank you.

6. Hi,
   I am not sure if this is what you are looking for but the price is
right. My group produces the GAMESS ab initio package which includes
several semi-emperical wavefunctions (AM1, PM3...). It runs on most
workstations and on PowerMacs. If you are interested you can check out
our WWW page at http://www.msg.ameslab.gov/   or send an email to
Mike Schmidt at mike@si.fi.ameslab.gov to request a copy. There is no
charge, but we do require that you sign a simple license agreement.

7.    I think Mopac95 is a good choice. It is easy to get
the source code on the Internet. In addition, there are
few freeware of drawing molecules and those data format
could be converted by "babel"(also freeware).


xxx   name withheld on request.

8.   Spartan is coming out with desktop computer versions which, although
not cheap, probably cost about the same as many textbooks students are
accustomed to paying for.  I would appreciate receiving a summary of
responses to this question.

10. MacSpartan (PowerMac version) could do the job. It includes quantum
mechanics (ab initio and semiempirical) and molecular mechanics methods.
Its high-end graphics provides great visual teaching tools
for organic chemistry. It prices at $299 (US & Canada academics).
Along with it, Wavefunction also offers publications related to your
purpose - teaching in organic chemistry:

(1) Educational CD-ROM: "Visualization of chemical structures and reactions",
    (facusing on organic chemistry), by Tom Hehre, Lonnie Burke,
    Wayne Huang, Warren Hehre, 1995.

(2) Self-guided Tutorial: "A MacSpartan Tutorial", Wavefunction, 1996.

(3) Experiment book: "A Laboratory Book of Computational Organic Chemistry"
    by Warren Hehre, Wayne Huang & Alan Shusterman, 1996.

***************************************************************************

Here is my summary - and many thanks to all that wrote to me and helped.

>1. Does anyone know free semiempirical calculation program, that are not
>   versions of ampac and mopac.

There is a program called VAMP, that should be free up to VAMP 4.5.

>2. Which was the last free version of ampac?

All the MOPAC programs with single digit extensions, e.g. MOPAC 5, MOPAC 6,
MOPAC 7, are public domain, and are `free'.

>4. On which ftp-server can I find these programs?

You can find free versions of MOPAC6 & MOPAC7 for DOS, LINUX and sources
at www.ccl.net. Look in the webpage of CCL.
I couldn't compile MOPAC7 for the SGI.

A word to VAMP: I know it, as we use the newest version, that you have to
buy, on our
workstations in the university. If you can handle MOPAC5 to MOPAC7 you can
handle VAMP
also very good. AMPAC is also as suitable, but in my oppinion the available
versions on
ftp are to old, MOPAC is much newer. MOPAC is now developed also for
buying, but if you
look in chemical newspapers, there are still a lot of articels, that were
calculated with
MOPAC6. I personal run MOPAC6 on my PC by using DOS and by using LINUX. I
have to point
out the version compiled for LINUX is faster. The general handling is the same.
The geometric input for the molecules and nearly all keywords are the same.
So MY PERSONAL hint for your problem "no money - good results" is use MOPAC.

A friend of mine used archie and gave me the following. here you can find
MOPAC and related
things.

If you are looking for a visualistion tool for your outputs try CASCADE V2.
This version is
in the moment only for DOS/OS/WINDOWS available, but we hope that up to
february we have
CASCADE V3 running, it should run with DOS/OS/WINDWS and X. And the most
interesting
it is copyrighted as GNU - that meens free for all! For more infos about
CASCADE, mail
me, as I am a member of the CASCADE Development Team. As we do not have the
chance
to test CASCADE V3 on a X for MACs, I do not know if it will run on MAC
too. Here is the
text I mailed to the CCL some weeks ago.

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
++++++start

Dear CCL users!

We proudly announce our program CASCADE:

Here the readme-file

****************************************************************************
*****

C A S C A D E   V 2     (DOS/Win/OS2 VERSION)
==========================================================================
>> Cascade Aids Semi-empiric Calculators Access Displays Eventually :-) <<
==========================================================================
Cascade V2 is a shell which converts semi-empirical data (from programs
like MOPAC, AMPAC and VAMP) into several 3d graphic formats. It thus
enables the user to visualize the resulting molecule geometry. The supported
display programs are:
  3DV, Chemview, JMR, MOLWIN, MV, PC MODEL, PLUTON, POVRAY,
 RASWIN.

Ralph Puchta            (puchta@anorganik.chemie.uni-erlangen.de)
Michael Reichenb"acher  (reichenb@mi.uni-erlangen.de)
--------------------------------------------------------------------------
Please use the program install.exe to uncompress cascade.zip,
otherwise you have to set the environment variables CASCADE and AWKDIR
manually.
If you have used install.exe, you can use cascade.bat to start cascde.

****************************************************************************
*****

You can get CASCADE via ftp:

ftp://www.ccl.net/pub/chemistry/software/MS-DOS/cascade

ftp://uni-stuttgart.de/pub/scivi/cascade

You have to get 3 files:

cascade2.rea -> the readme file (you have read in *)
cascade2.zip -> the program
install.exe  -> this part installs CASCADE in the right way on your PC

We hope that you will enjoy it.
If you find any bugs or have any problems, think something should be changed,
should be added or any thing else, feel free to contact us.

We wish all CCl users a merry Christmas and a happy new year 1996.

Ralph Puchta

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
++++++end

I think you know most of the supported programs and you know, that they are
free or not
to expensive, too.


If you want to combine the education in ab initio and semiempirical calculation,
you can use GAMESS, that can do both, as they included parts of MOPAC. But
I never tried
it myself, for more infos try:

Mike Schmidt via e-mail (mike@si.fi.ameslab.gov).

As far as I know it runs on PC only via LINUX. About MAC I do not know anything.
I fear GAMESS will not be supported in CASCADE V3, as I had not the time to
get into GAMESS.

To run Linux you need a PC 386 or higher, for running MOPAC5 you need also
as 386
or hihger. I personal run my semie-empiric calculations at home on a 486 DX
2/66, and
in order to calculate e.g. C60 it lasts a night.


I hope this helped a little bit.

Many greetings

        I would like to compare quadrupole moments computed by 
Gaussian92/DFT with moments computed by another code.  Gaussian
however, does not compute a non-traceable quadrupole moment for 
a homonuclear diatomic.  (I believe some matrix rotation is 
required to give me a 'Buckingham type' traceless quadrupole, but
I am not sure.)  Is there anybody out there who knows how to 
transform 'g92' quadrupole moments to traceless quadrupole moments?

Seems you want to a dynamic constrain exercise. Coordinate driving which
allow one to generate a list of molecule by promoting its geometrical
parameters (can be more than one simultaneously or in sequence) of a
single structure, but this requires optimization of some sort, at least MM.

Hi!

I am trying to test ADF 2.x on an old system. Unfortunately, I had problems
installing the software and running the samples. After some playing
around with options, I was able to compile the software, but I get a cryptic
ADF error message. Unfortunately, the machine is stand - alone, and
before I try some maneuvers to give the ADF people access, I would like
to know:

Has anybody had any success mounting and running ADF 2.x on
an SGI R4000 running IRIX4.05f?

Thanks

The output from IRC computations done with Gaussian 94 rev C.3 seems to be

have the output in internal coordinates:  is this possible?

Wouldn't it be simpler to just load it into Chem3D directly and create the 
stereoscopic views there, rather than going through all the other file
formats?  Chem3D will add the bonds back in for you, too if you want.

Hello,  There was a recent query about getting a stereo image from a set of
"disembodied atoms", evidently Cartesians with no connectivity (no bonds
specified). The program MolWin, for IBM compatible PC's, will accept
Cartesians and give a mono or stereo picture. It will also accept Gaussian output
(G92; G94 output may have to be modified) and, for freq jobs, animate vibrations.
The pictures can be exported to WordPerfect, annotated and printed.
  MolWin was written by Dr Pavel Ganelin of the Catholic University of America,
48ganelin@cua.edu       It should be obtainable from
  oak.oakland.edu/simtel/win3/chem/molwin23.zip

For jC(left), it's cC on the right side

For jC(right),     cC on the left



As the current is turned on, the "right" and "left" concentrations change 
until the two fluxes become equal (i.e. stationary situation is 
established). (I am sure it's more complex in reality, you may never 
actually reach the steady state).

                    Hypercube, Inc. 
                presents an Introductory
                   HyperChem Workshop 
               on Computational Chemistry



                  April 10 -12, 1996
              Ready Serve Computer Center
              Santa Clara, California, USA




          

HyperChem is like any other powerful tool: the more you know about it, the 
more you get out of working with it.  For those who wish to learn more 
about the methods of molecular modeling and computational chemistry, 
about the ways of working with HyperChem, and about the range of 
problems you can now tackle on a PC, Hypercube, Inc. (the developers of 
HyperChem) offer an intensive three-day introductory workshop on 
molecular modeling with HyperChem.  
The workshop is pragmatic and application-oriented and makes no 
assumption of previous computational chemistry experience.

Workshop Objectives

The workshop will introduce you to techniques for working efficiently with 
HyperChem and other Hypercube's products, provide a pragmatic user's 
guide to the scientific methods behind HyperChem, and include many 
hands-on exercises based on practical molecular modeling  problems.

Workshop Outline

Day 1.	Morning:  	Overview of Computational Chemistry 
			Techniques;
			HyperChem Graphical Interface
	Afternoon:	Molecular Mechanics Methods
			Laboratory session

Day 2.	Morning: 	Approximate and Semiempirical 	
			Molecular Orbital Methods;
			Ab initio Molecular Orbital Methods
	Afternoon:	Frontier Orbital Theory: Examining 
			Molecular Reactivity;
			Laboratory session

Day 3.	Morning:	Molecular Dynamics;
			Molecular Spectroscopy;
			QSAR/Group Contribution Methods
	Afternoon:	Laboratory session (optional)



Costs and Venue


The cost for the three-day course is $995 US (Academic and Government 
discount price is $795 US). For early registration (before March 15) the 
price is $925 US ($725 US - academic).  This covers the cost of course 
materials, coffee, lunches, and a PC to work on for the duration of the 
course (each participant will have his/her own machine). The number of 
participants is limited, so that extensive interaction with the workshop

I would be grateful if someone would point me to preferably online
documentation giving the standards (IUPAC?) specifying the atom
quadruples for polypeptide dihedrals.  This is not entirely trivial,
since the order of the atoms defines positive rotation of the dihedral,
and for some (e.g. proline N-CD or CD-N?) the choice is not clear.

Thanks,

I'd also like to know about an online version of this, but the standard
paper version is of course:
        IUPAC-IUB Commission on Biochemical Nomenclature.
        Abbreviations and Symbols for the Description of the Conformation
        of Polypeptide Chains
        Biochemistry 9, 3471-3479 (1970)
also published in
        J Biol Chem 245, 6489 (1970)
        J Mol Biol 52, 1 (1970)
