I have a request. We are doing vibrational mode calculation for large molecular crystals. We can obtain the frequencies and the eigenvectors. However, the program can not do symmetry analysis and tell us the IrrRep for certain mode. Does WebMo has this feature? For example, take eigen vectors of vibrational mdoes as an input and tell the IrrRep and maybe also run the animation. I can convert our output to any format. If WebMo cannot, is there any other utility can?

WebMO only parses the information that is given by the computational program, and does not do any independent calculations on its own. Thus, if the program does not provide a symmetry analysis, WebMO will not be able to provide that information either.
If you wish to display an animation of the vibrational mode, then WebMO may be able to help. If the computational program is one of those that we support (Gaussian, GAMESS, MOPAC, QChem, NWChem...) then you can import the output file, and visualize the results within WebMO.
If the output file is NOT from one of those programs, then WebMO cannot import the file directly. You would have to try can convert the output to one of those formats, etc.

Hello, I am struggling to find transition state with gaussian, for example SiH2 + H2 ---> SiH4, and I don't what steps to do. I appeciate to have assistant, thanks a lot

The output for the vibrational modes has a "?" in the symmetry field, such as ?A, ?B and so forth. We are running WebMO 16.0.005e. Has anyone else encountered this problem? Thank you.

we have problems visualizing IR Spectra with WebMO from G09 calculations. According to tech info this should be possible, but how?

Please post a sample output file for a failed calculation. This seems to work fine in all our testing and no other users have reported this problem.
