Subject:  MOPAC:transition dipole


I am interested in the calculation of
transition dipole moments between the
excited states and excited state dipole
moments for various molecules. This possibility
is specified in the MOPAC capacities from
the MOPAC manual, but no further indication
is given. I would like to know if there is
a specific keyword for that in the program
or if it is necessary to make calculation
by ourselves from MOPAC results on 
molecular orbitals.
Thanks a lot for your attention!

        Netters,

        The codes in "Numerical Recipes in C" (or your favourite language)
could originally be purchased from the publishers.  It's been a while, I
wonder if anybody knows if ordering a disk is still the only way to get
these codes (except entering them yourself from the book), or if they are
now available on the net.

        Thanks in advance,

Subject: Freeware for NMR processing



Dear netters:

  It is a pleasure to announce that version 3.1.2 of the NMR processing program 
SwaN-MR is available, as a compressed-self-expanding file and a swaninfo.txt 
file, (via anonymous ftp) from the following repositories:

qobrue.usc.es
directory /ftp/pub/nmr/SwaN_MR_312

www.ccl.net
directory /pub/chemistry/software/MAC/Swan-NR

Or from the following gopher server:

gopher://www.ccl.net:73/11/software/MAC/Swan-NR

SwaN-MR is a FREEWARE program for the Macintosh (with FPU) and PowerMac. It 
processes and analyzes NMR spectra (1D to 4D, from Varian: XL, VXR, Gemini, 
Unity. Bruker: AC, AM, AMX. 20-bit files: Nicolet. Binary files: GE, MacFID. 
ASCII files: real part of transformed spectra). It is also very useful in 
annotating, printing and presenting spectra. The program has been written by:

Dr. Giuseppe Balacco
MENARINI RICERCHE s.p.a.
Via Sette Santi, 3
I-50131 Firenze
ITALY
phone: 39 55 56 80 339
fax:   39 55 56 80 419

In order to use SwaN-MR you need to write a SIGNED AND DATED LETTER (no fax or 
e-mail messages) to Dr. Balacco requesting a LICENSE. There is no fee for the 
license.

The program's capabilities include:
Weighting (9 different window functions)
FFT up to 256K points (real, complex, hypercompex, etcI)
Phase Correction (1 manual and 2 automatic options)
Magnitude representation
Baseline Correction (6 options, including 5th degree polynomials and 
trigonometric series)
BasePlane correction
Integration (manual and automatic in 1 and 2 dimensions)
Least Squares Fitting (to Lorentzian or Gaussian functions)
Quanto-mechanical simulations
Fast Linear Prediction
Digital Solvent Suppression
T1 calculation (inversion recovery)
Spectral Editing (algebraic addition and much more)
Symmetrization
Spectral simulation (up to 9 non-equivalent 1/2 spins -40 in total-)
AND MANY MORE...

WHATUS NEW IN VERSION 3.1.2
	in the historical part
1. Loading 2D files from disc is more than twice faster.
2. A progress-dialog in most converters.
3. The RResultsS window can mantain an almost unlimited quantity of text.
4. More compatibility with Bruker DRX files.
5. The command: Full Atomatic Baseplane correction.
6. The guest spectra donUt disappear with the commands RLoadS, RExtractS, etcI
7. The command RRaw DataS is more flexible.
8. A new converter for spectra in the ASCII format.
9. You can continue using keys like <+>, <->, etcI even when phasing.
10. The command TView/IntegralU.
11. Solvent Suppression is faster and friendly with background applications.
12. Digital Phase is faster in 2D spectroscopy.
13. <Option> + TSymmetrizeU = the new command TTransposeU
14. You can phase directly a 2D spectrum with the clock!
15. The manual has been written in English !!!!!
16. Many small errors have been corrected.

	in the spin simulation part:
1. More correct spin system simulations.
2. Error Analysis.
3. The duck icon performs a different action.
4. Fitting speed is orders of magnitude higher and does not depend on the TpullU
parameter.
5. J values may be linked one to another.
6. Lines may have either Gaussian on Lorentzian lineshapes.
7. There are 5 new fitting options.

  Happy NMR processing

Subject: Open Postdoctoral Position


Dear Netters,

I have an immediate opening for a postdoctoral researcher in my laboratory.
Funding is available for three separate projects, and the applicant should
identify which of these projects is most appealing.  Project One deals with
molecular modeling of thermo-oxidative stability and solvent (water)
permeability associated with polymers (e.g., polyimides).  First-hand
knowledge of polymer modeling software (e.g., Insight/Discover or Cerius_2)
and applied quantum mechanics is highly recommended.  Project Two deals with
studies of the deposition and catalytic reaction of gases onto metal (Cu,
Ni, etc.) surfaces using both classical and quantum approaches.  Project
Three deals with de novo computer-aided design of chemotherapeutic
inhibitors using receptor mapping,  QSAR and 3D-QSAR approaches, neural nets
and genetic algorithms, and combinatorial libraries.  Projects One and Two
have the highest level of priority as the present time.

Funding for this position is budgeted for two years, although initial
appointment will be made for one year with renewal for the second year
pending (i) continuation of the grant for the second year by the funding
source and (ii) successful progress in the first year of work.  Salary is  >
$25,000 but is negotiable, and the position pays full fringe(e.g., medical)
benefits.  The applicant would be joining an active and aggressive reseach
team which already includes three postdocs, with excellent opportunities for
professional growth and for interactions with industrial collaborators (this
means good job prospects!)  The computational facilities and excellent (12
SGIs plus numerous other workstations and PCs with peripherals), and
available software includes Insight/Discover, Cerius_2, Macromodel, Spartan,
Semichem, Gaussian 9X, Sybyl (CoMFA), BrainMaker (for neural nets), and
Pirouette (for regression, etc.) plus assorted plotting, drawing, and word
processing programs.  Also, in July/August 1996 we will be moving  into a
large and modern computational-chemistry laboratory located in the newly
constructed Center for Molecular Electronics adjacent to the Chemistry Dept.

Please mail and/or email your full resume and/or CV including list of
publications and the names of three professional references to:

Hello,

I'm not very familiar with frequency calculations; I apologize if this 
is a very dumb question.

In Gaussian94, for the optimized geometry of LiH (HF, 6-31G*) I obtain 1 
vibrational mode of SG symmetry with a frequency of 1416.1757 
wavenumbers and a reduced mass of 1.1293 AMU.
I can't understand that latter value. Why is it unequal to 1/ [ (1 / 
7.016) + (1 / 1.00783) ] = 0.88124 in which I used the atomic masses of 
Li and H?

Thanks for your attention,

Roger

Subject: Re: CCL:PRONUNCIATION ON CONFORMER


Peter,


I don't have a good Latin dictionary here, but a quick squint at the 1966
edition of Merriam-Webster's dictionary (largish, but certainly not the
OED) makes me a bit skeptical of your etymology, though I confess I
sometimes used to say CONformer.


First some background.  In Latin

	conformare is the verb,
	conformation, conformatio the noun (I don't have my
Latin-grammar-for-idiots-like-me handy, so I can't spot which declension)


>from which we derive our English words

	to conform
	conformation
	conformer.

I presume their only difference is one of gerund-ness, so that the verb is
the ultimate root.  In Latin, I see no reason why the stress wouldn't be on
the penultimate and antepenult syllables, so conforMAre and conforMAtion.
I would like to hear from someone who knows Latin on these points!


Now in English, the dictionary gives the following pronunciations.  I'll
completely capitalize the syllable with primary stress, and separate the
secondarily-stressed syllable by //, and optional secondary stress by ||.
Be aware that syllables for spelling and phonetic syllables are evidently
not the same, even in a given word.  I am separating the (mostly) phonetic
syllables by blanks.  Notice the spelling isn't the IPA or anything close!

	con FORM			ME <- MF <- L
	con FOR mable			
	con FORM ance
	con FOR mer
	con FOR /mism/			F
	con /form/ aBIL i ty
	/con/ |for| MA tion		L

So the stress is shifting between the second and third syllable, and notice
the position of the "m" sound slides back and forth across that boundary.
I suspect for many of us that "m" sound gets doubled, so it ends up on both
syllables simultaneously.


What is going on?  The etymologies are sketchy so I'll guess.  The verb
"conform" comes into English quite early, and then mutates into adjectives
and nouns ("conformable", "conformance", "conformer") but retains the
stress on the second syllable.  This is certainly where I would stress the
modern French, so perhaps I've guessed wrong about the Latin stress.
"conformism" comes from modern French, so keeps its secondary stress.
The rule breaks at "conformability", when I suspect evolution lets English
stress rules dominate.  "conformation" is in English a straight borrowing
>from Latin, and so retains its (classical?  surely Vulgate) pronunciation,
allowing for compression of the last four letters into one sound.


Notice that in no case is the stress on the first syllable.  Whether the
chemical sense of the term derives from "conform" or "conformation" --- and
I would vote that it's an extension of the sense of "conformer", as defined
in 1966 ("one that conforms") --- you can't use it to justify what I agree
may be the most common pronunciation.  I suspect CONformer comes by analogy
to ISOmer.  It seems to me one might wish to retain the different stress to
distinguish among the different connotations of the word, but if so that
usage will be established over time.  This is a case where everyone
world-wide votes with their mouths ;-)!


But Peter, I'm not giving up on the plural nouns data and media (and
indices, and formulae, and basilica, and . . . )!

Subject: HF-ECPs for DFT calculations


Hello.

laurent JOUBERT (joubert@ext.jussieu.fr) wrote asking about ECPs for     
lanthanides for use in DFT calculations, and whether or not the HF ECPs
work correctly.

I cannot address the first question, but the second one was addressed in the 
recent paper by Hay and coworkers

Russo, T. V.; Martin, R. L.; Hay, P. J., J. Phys. Chem., 1995, 99, 17085.

The basic consesus of the paper is that while the ECP itself may be used 
with good reliability, at least when compared to all electron calculations, 
the HF basis set is probably not reliable with DFT calculations.

Hi,
	We have been determining some transition state structures
using AMPAC and the keyword LTRD.  Sometimes we get two or three
negative eigenvalues and have to perturb the structure to get to 
only one.  There are times when one of the smaller negative eigenvalues
has a very large error associated with it:  for instance, -27 +/-
80.  Recently we found(?) a transition state with one negative 
eigenvalue but a large error on the smallest of the positive
eigenvalues.  Question:  How does one interpret these large errors? 
Should we worry that a large error in a positive value may not really
be a transition state?  Thanks for your help.

oops, I should have said "the primary stress on the first syllable",
not "the stress on the first syllable".  And note the option of stress on

Sorry if I've added to the confusion ;-),

Why just MD simulations? I'd love to see a general file format for
*all* computational chemistry applications. Wouldn't it be nice
to be able to tell your ab-initio code to calculate the energy
for the 42nd configuration of an MD trajectory?

There is of course the small problem that various programs need
various information, and that you can never know in advance what
information other programs might possibly need. Therefore a general
file format would have to be extensible: each file would consist of
sections starting with identifying tags, and every program would
ignore tags it doesn't need or understand (those who happen to know
TIFF will know what I am talking about...). There would be standard
tags and program-specific tags. Such a file format can be extended
arbitrarily without giving up compatibility with old programs.  I've
used this approach a long time ago in a word processing program and in
spite of many updates the first version can still read the files
written by the latest.

Another important feature is to have both a text and a binary
version of the format, plus a simple program to convert between
the two.

Probably something like this can be implemented on top of
existing standards/libraries like netCDF. But defining a really
good format will take a lot of work, so I suppose it won't
happen any time soon :-(

Sorry folks,

I was either short-circuiting or subconciously joking: basilica is Greek!
basilica <- basilikos <- basileus or "early Christian church shaped like
Greek royal palaces"/"royal palace" <- feminine singular of "royal" <-
masculine noun "king".

Thanks to Konrad Hinsen for basilikos and no, I don't have Liddell and
Scott here either so I can't verify my transliteration of basileus.

Stay tuned for CEX (Chemical EXchange).  This is being assembled
quietly by a small consortium, and we want to get some sample
applications out to polish the implementation before announcing
it to the world.  

The impetus behind it is Frank Brown at Glaxo;  Dave Weininger
of Daylight Software has put together an underlying language
for passing data, and a few programs (RasMol, DGEOM) know how
to "speak" it already.  I'm beginning a MacroModel port.  

It's not so much a file format as a chemical database API.  Using
the API, one can write into a file or read from a file, or 
read/write to/from any CEX stream (which might be a program, for 
example).

Hopefully, sample implementations will be available within a
few months.  In the meantime, see:
