Summary: Orbital Viewer
Dear Collegues,
here is the summary of my question concerning Gaussian orbital
viewers for Windows NT. We need such a tool for our Quantum
Chemistry Laboratory. This is a course about quantum chemistry
in the internet. If you're interested please visit our web-page:
http://qcl.theochem.tu-muenchen.de/
Thanks to all who replied.

Original question:
Dear Collegues,
we are seeking for are free orbital viewer for Windows NT,
which can display MOs calculated by Gaussian. We need it
for educational purposes. Also suitable would be a program,
which can build a VRML file, as molden does, but in command
line mode. We would run that program on our Unix Server and the
VRML-file is just transferred to the students PC, which will
display it.
Thanks in advance
Philip

Answer 1 (Martin Leboeuf):
Hallo !
Fuer Unix, schlag ich Ihn VU vor :

VU kann VRML schreiben. Fuer Chemie Beispiele :

Gruss, Martin.

Answer 2 (Wolf-Dietrich Ihlenfeldt):
Haben Sie schon einmal einen Blick auf OrbVis
http://www2.ccc.uni-erlangen.de/services/orbital/index.html
geworfen?
Wir benutzen als QM-Programm VAMP, aber eine Anpassung
an Gaussian ist sicher nicht unmoeglich.

Answer 3 (Jose I. Garcia):
Dear Philip,
Here are several possibilities:
* GOpenMol (http://laaksonen.csc.fi/gopenmol/gopenmol.html).
It runs under Windows 95/98/NT, and it is able to display
nice images of gaussian cube files, and hence of M.O. also.
It is my favorite for M.O. display, but it is not able to
export images to VRML files.
* Molden (http://www.caos.kun.nl/~schaft/molden/molden.html)
It runs mainly on Unix machines, but the last version can
also run on Windows 95/NT machines (however, it requires
a X-Windows Server software installed to run; see the Molden
page for details)
* Chem3D Ultra (from Cambridge Software). This is commercial soft,
but not expensive for educational purposes. It is able to
display gaussian cube files, but it do not export to VRML
files.
I hope this helps you.
Regards.
Jose I. Garcia

Answer 4 (Max Valdez):
Hi Philip:
I think molden is the only good and FREE program that can do that, and as i
can
understand, you don't have graphic terminal i recomend you to put at least one
xterm emulator, as you need to see the orbital before building a VRML file of
it,
or you will never be sure of what image correspond to a given density value.
there is one free xterm emulator in http://www.microimages.com/ and there
are
some commercial emulator that work better if you want to spend some money.
Best Regards
Max

Answer 5 (Jose Conceicao):
Hi Philip
Here is an email message I received from other workers using Gaussian 98W
(windows version) about viewers. Hope it works for you.

Answer 6 (Leif Laaksonen):
Philip,
Please have a look at gOpenMol at:
http://laaksonen.csc.fi/gopenmol/
I'm working on a VRML filter, which will be included in the next release.

Answer 7 (Serge Pissarev):
Molden for Windows NT can export the orbitals into VRML. It uses X-server
to perform drawing. Updated version can import the Gaussian wavefunctions.
I do not know others that *DO NOT* use X-server. If you do know them,
particularly the ones that could operate with both Gussian and GAMESS-US
wavefunction, please, let me know (summarize in CCL?)
----------------------------------------------------------
Answer 8 (Gijs Schaftenaar):
Dear Philip,
Molden can run VRML in the commandline mode:
molden -V vrmlfile commandfile
commandfile:
some title
file=gaussain.log space=0.1 vrml2.0
(you could use vrml as keywor to specify vrml1.0)
There is a molden vrml orbital/density service on our web site that uses
this setup (URL: http://www.caos.kun.nl/~schaft/molden/moldenservice.html)
Secondly, there is a Windows95/NT version of molden, it needs a Xwindows
emulator like xwin32 to run.
Have a look at URL:
http://www.caos.kun.nl/~schaft/molden/windowsnt95.html
PS: be sure to download both zip files:
ftp://ftp.caos.kun.nl/pub/molgraph/molden/bin/molden_windows_nt_95.zip
ftp://ftp.caos.kun.nl/pub/molgraph/molden/bin/molden_windows_nt_95_update.zip
The molden home page is at:

Best Regards,
Gijs Schaftenaar

Answer 9 (Alexander Klinsky):
Why dont you use Molden for Windows NT?
I have been upgrading recently my port on the official molden server from
Gjs Shaftenar to the latest 3.5 version from second June 1999.
