I wondered if WebMO support for Gaussian 03 is forthcoming?

Yes, support for Gaussian 03 will be in the next WebMO release.

Does Gaussian03 have semiemperical methods including dorbitals? 
schmidt
 Posted on Tuesday, February 21, 2006  1:02 pm:  
I don't believe that Gaussian03 supports MNDO/d, or any other semiempirical methods with dorbitals. I believe among the only available package that supports these methods are MOPAC 2000/2002, available from Fujitsu.

It sounds like your geometry optimization is not converging. Try changing the optimization thresholds, or use a different optimization algorithm. See the Gaussian manual for details.

Sorry, I'm just learning about this stuff. My adviser describes this loop as an energy valley. I'm trying different Opt options but the jobs take around a day to fail. Could you point me towards a more specific direction? Thanks

Can anyone help me set up a PCMONIOM calculation? When I try to use SCRF keyword with an ONIOM calculation I receive an error that says that SCRF cannot be used with ONIOM. I read briefly in some other forum that the work around is to use an iOp keyword so the line in the input file looks like this: # ONIOM(BLYP/631G(d)/Auto TD=(NStates=20):AMBER) IOp(5/94=0) when I look up IOp(5/94=0) in the online manual it states that setting the flag for 5/94 = 0 will set up a standard PCM calculation, so what I would like to know is what does "standard" refer to? Water as the solvent? If anyone has any information about running PCMONIOM calculations using Gaussian 03 it would be appreciated!!! Thanks!

The bonds displayed in WebMO are rather arbitrary, and are for display purposes only. They have no intrinsic chemical meaning, and are not used in the calculation.

This problem actually isn't quite so simple due to the subtleties of the zmatrix coordinate system at angles around 180 degrees. What computational problem are you using? What angles are you scanning between? A robust set up for this calculation may require the use of dummy atoms, and manually modifying the zmatrix.

 Posted on Friday, December 05, 2008  12:20 pm:  
Definitely the 180 problem. The easy fix is to simply start your scan at 179 degrees to avoid your problem. The 'right' way is to define a dummy at off the bond axis, and use this dummy atom as the reference point of the scan. The choice is yours.

Hi to everyone. I'm a Masters student and I would really need some help with a transition state search with Gaussian03. The molecule is a cation and it splits up in a neutral molecule and a hydrogen cation. I've tried the methods QST2, QST3 and TS, with RB3LYP/631G(d) but I get errors or the transition state doesn't converge. I am thinking that the problem might be the positive charge, but I don't know how to deal with it. Thanks a lot in advance for your help.

Hello everybody, I try to calculate electrone densities in excited states and their differencies in Gaussian 03. Could anybody tell me what is the meaning of Transition=N option? I thought that it should be a difference between Nth excited state electron density and ground state electron density. But the results I got look like a density, not their difference. I am suspecting myself, that the input command is not correct. My input command was: # td(root=1) B3LYP/631G(d,p) IOp(6/29=1) IOp(6/22=3) density(Transition=1) cube=density nosymm Geom=AllCheck Guess=TCheck test Can I calculate the ground state electrone density like this? # td(Root=0) B3LYP/631G(d,p) IOp(6/29=1) IOp(6/22=3) cube=density nosymm Geom=AllCheck Guess=TCheck test Actually, both these input commands seem to give the same density cube files in result. Can someone give me a comment to this? Thanks in advance.

Alternate radii for each atom for use infitting potentials may de input via the ReadRadii option. What does mean?

The people who use WEBMO for Gaussian in a cluster (computers with 2 quadcores, i.e. 8 CPUs for computer). Is it easy to send calculations choosing 2,4,8 cores? (or the restriction is 4?).The queue system does it work properly for 16 computers? Is it easy to install? Best regards,, Albert

With WebMO, it is easy to run SMP parallel jobs with either WebMO Pro or WebMO Enterprise. You can choose as many cores as you have on each node. As for the queues, there are two options. If you have a small number of computers, WebMO Pro can distribute the jobs between all the computers without installing any additional software. This works great for say ~515 computers, and does not require a shared file system. For more than 1015 computers I would definitely recommend WebMO Enterprise. Enterprise can interface with a real, external batch queuing system such as PBS/Torque (which is free!) and is perfect for running on a "real" computer cluster with a shared file system.

Hello All, I am trying to run an optimization for a molecule (an intermediate) that is covalently bonded to an enzyme (from the crystal structure) before calculating the charge distribution. I would like to do a partial optimization, so that I can optimize just the bond lengths without changing the bond angles. I've tried two other optimizations (once using B3LYP/631G* opt and once using HF631g* opt=AddRedun in the route card) and each time the optimization causes internal hydrogen bonding within the ligand, which I don't want. Any idea on how to prevent this internal hydrogen bonding? Also, do you think it's necessary to run an optimization step at all? Could I just go ahead and calculate the charge distribution for an unoptimized molecule? Any thoughts would be greatly appreciated!

hi i am trying to do the frequency test for 7 azaindole (having 15 atoms) using gaussian 03 (windows) program, and mp2/6311++g** level of theory. i make different jobs with different number and capacity of rwf files and memory, but in all cases jobs had been died! There are not problems of disk space. please help me. best regards

Hi' I want to get MO coefficient at reactive sites of a molecule . I use from yhe keyword of POP=regular or POP=full, and I take this part in out file; 96 97 (A)O (A)O EIGENVALUES  0.33026 0.29483 .... 1 1 C 1S 0.00042 0.00029 2 2S 0.00017 0.00019 3 2PX 0.00327 0.02460 4 2PY 0.00920 0.14166 5 2PZ 0.01784 0.20415 6 3S 0.01267 0.00385 7 3PX 0.01027 0.01634 8 3PY 0.01918 0.13449 .... 9 3PZ 0.02527 0.18949 ... 10 2 C 1S 0.00033 0.00076 11 2S 0.00219 0.00166 12 2PX 0.02370 0.00989 ..... here the eigenvalue of 97 is HOMO and we have some numbers for every atom, but I want just a number for every atome in HOMO or LUMO, I express my thanks for youe time and help.

Dear Sir, How one can calculate the solvation free energy using the SCFVac function in Gaussian 03W? for example: HF/631++G(d,p) SCF=Tight SCRF=(PCM,Read,Solvent=Cyclohexane) Test (for methane) ﻿ Waiting for your reply, Regards, ﻿Alex

If you right click (or Control Click) and atom in build or adjust mode, you can change the charge.

Hi my gaussian job is not going to stop at the place where its intended to stop. it takes much longer than expected and produce .out file which is more larger (in space) than other normally completed .out files. why its happening ??

Hi, Is there any way to get Gaussian 03 or 09 to print the dipole matrix? I am trying to calculate transition dipole moments between different excited states, semiempirically. From my understanding, I could do this with the transition density matrix and the dipole matrix. Thanks!

Hi, While the geometry optimization is running, Gaussian crashes/terminates without an error message. Final part of "population analysis using the SCF density", Gaussian cannot enter the Link 702 (L702.exe) which lead to termination of the run?

I can submit a G03 job, but it stops (with no error message) essentially immediately (in the middle of printing the job options/input stream for the file header). This doesn't appear to be a WebMO issue, but I want to make sure I'm not missing is some sort of time variable I need to set. I'm running on a Linux (CentOS 7) cluster with external PBS queueing (Torque 2.5.13 and Maui 3.3.1).

Steve, Just to make sure, upgrade to WebMO 16.0.004. I made some bugfixes that I don't that are related, but it cannot hurt to check. When the job fails, also "mouse over" the "failed" on job manager to see if it tells you if the jobs was killed by WebMO.
