Dear Serdar,
You can find such a program at: www.phys.ubbcluj.ro/~vasile.chis/group
It is written in Python and runs under Linux or Windows. In the last case
you need to have Python installed on your computer.
The program will extract the symmetry, wavenumbers, IR intensities and Raman
activities, as well as the redundant internal coordinates contributing to
each normal mode. In order to have the contribution to normal modes you need
to include Freq(intmodes) in the route section of your job.
When running the program you will be prompted for a scaling factor, the
exciting laser wavenumber and a threshold for the contribution of internal
coordinates to normal modes. This threshold will be subsequently reduced
until at least one redundant coordinate is printed. Thus, the output file
you will contain both the unscaled and scaled wavenumbers, Raman activities
and intensities.
Raman intensities are obtained according to:
[1] P.L. Polavaru, J. Phys. Chem. 94 (1990) 8106.
[2] V. Krishnakumar, G. Keresztury, T. Sundius, R. Ramasamy, J. Mol. Struct.
702 (2004) 9.
[3] S.D. Williams, T.J. Johnson, T.P. Gibbons, C.L. Kitchens, Theor. Chem.
Acc. 117 (2007) 283.
A non-uniform scaling is performed according to Scott and Radom:
A.P. Scott, L. Radom, J. Phys. Chem. 100 (1996) 16502.
Run the program using the following commands:
Windows: python vibrational_modes.py gaussian_log_file
Linux : vibrational_modes.py gaussian_log_file
The output will be written in a text file that, subsequently, can be
imported in a spreadsheet.
An example of output is given bellow:
# Nr Sym Freq[cm-1] Freq_scaled[cm-1]
IR_int Raman_Act Raman_Int internal coordinates

Sent to CCL by: "Serdar Badoglu" [sbadoglu-$-gazi.edu.tr] Hi CCL'ers,
Do any of you have / know an excel macro / a little program to extract
calculated frequencies, infrared intensities, and Raman activities from
Gaussian log file? I don't need the complete spectrum generated, I only need
the mentioned data of vibrational modes. I'm really tired of switching
between windows and reading and typing the data into spreadsheets.
