G98W cannot work parallely on Windows platform because G98W was not programmed
for parallel computations. But G98 can work parallely on dual processors Linux
systems. That is to say, you need install Linux on your new system and get a
linux version of G98.

If you have any decently sized athlon cluster, AMD is willing to get
pretty involved.  Several AMD guys came out to our location and we were
the smallest installation in that list (Calvin College, 18 nodes).

I would be grateful if someone can suggest to me the software (freeware or
commercial) 
which predict the UVCD spectra of a given molecule. 
Many thanks!!

I use R for all my statistics

    http://www.r-project.org/

It runs on many different platforms (I've personally used it under both
Linux and Irix, but there are also Mac and Windows versions), and it's
a complete, modern, free (GPL) statistical computing environment.

Some possible negative points: it may be overkill for some purposes; it
does not have a graphical user interface; many modules are somewhat
indigestible to the non-statistician. However, I've been very happy with
it. The graphical capabilities are also good.

cheers,

Malcolm

Dear Francois,

did you check out

I am not a user (yet) but the website invoked my curiosity.
So please let me know you think it is useful for you and if you
could compile it.

Thanks, Best regards,

Hi,

Xmgr or the newer derivative xmgrace are able to do this. I use both on linux 
but I don't think its a problem to compile it for irix (source code is freely 
available). In my opinion xmgr is better for plotting but xmgrace is better 
for doing mathmatical operations.

Please have a look at: http://plasma-gate.weizmann.ac.il/Xmgr/ .There you 
will find both programs.

Best regards,


Bernd

New Molecular Orbital Software Package for Linux from FUJITSU
is available!

MOPAC2000 and LinMOPAC1.0 on 1 CD.

LinMOPAC 1.0 provides a simple graphical user interface (GUI) to the
semiempirical computational chemistry program MOPAC2000 version 1.33.
3D molecular visualization and a simple MOPAC setup dialog make running
experiments easy even for inexperienced MOPAC users:

* LinMOPAC reads and displays molecular structures from standard
   MOPAC ".dat" files.
* It provides visual controls for running a MOPAC job.
* LinMOPAC displays the final molecular geometry and molecular orbitals
   as well as the text MOPAC output file.
* Visual rendering modes allow for wire-frame, ball-and-stick, cylinders,
and
   space-filling molecular structure representations.
* Input files can be edited in text mode.
* No knowledge of MOPAC keywords is required to run LinMOPAC.
* The orbitals can be displayed using different surface representation
methods
   in both opaque and transparent models.

New version of MOPAC2000 (MOPAC2000 1.33)
* Bugs fixed
* Improved configuration Interaction module
* Dynamic memory allocation
* Increased speed and accuracy

We would like to invite you to evaluate the new product. Please send your
request for free CD to FQS Poland at ccs@fqspl.com.pl or at the address

Can someone explain the structure of a CAS registry number and how it is
generated?  According to the CAS web site, 336607-92-2 is the most recent
CAS Registry Number as of this morning.  I know there is no chemical meaning
or significance to the numbers, but what is each of the three fields and how
are the numbers assigned?

See http://www.cas.org/EO/regsys.html

Briefly:

o  The last digit is a checksum.
o  Everything up to the last digit represents a sequential number.  The
number above corresponds to the 33,660,792th item entered into their
database. (Approximately!  The numbers didn't quite start at 1, and just
because it was the 33.6 millionth item entered, that doesn't mean that all
of the other items are still present in the database.  Numbers are retired,
etc...)
o  The dashes are there just to make things look pretty.

I don't know about the first 2 fields, but the last field is an
"error-detecting" digit which is determined from the first two fields.  If
336607-92-2 is a valid number, then 336607-92-3 will not be a valid number,
and neither will 336607-93-2, etc.  I don't know whether it detects
transposition errors like 336607-29-2.

Can someone explain the structure of a CAS registry number and how it is
generated?  According to the CAS web site, 336607-92-2 is the most recent
CAS Registry Number as of this morning.  I know there is no chemical meaning
or significance to the numbers, but what is each of the three fields and how
are the numbers assigned?
Doug

The following is taken from an paper by Robert E. Buntrock, a specialist in
chemical information, entitled "Chemical Registries - in the fourth Decade of
Service" and presented at the 218th ACS National Meeting in 1999... The complete
address may be read at http://www.lib.uchicago.edu/cinf/218nm/218acs41.htm
and is part of the ACS Division of Chemical Information pages

"...The format of CAS Registry Numbers is intentionally unique. As mentioned
previously, the number is a serial number; the next available
number is assigned to the next new compound to be entered into the file. (As an
aside, Registry Numbers have disappeared from the file. For
example, formaldehyde – CASRN 50-00-0, or compound number "5000" -- is serially
the second compound in the file.) The last number is an
algorithmically assigned check character. The format is from two to six numerals
followed by a hyphen, followed by two numerals, followed
by a hyphen, and concluding with one numeral. As indicated, 50-00-0,
formaldehyde, is compound 5000, and 1746-01-6, dioxin, is
compound 174,601. ..."
