Resonance Raman using excited-state gradient


Clicked A Few Times
Is it possible to calculate Raman spectrum using ground state normal modes of the molecule, like it is done in ADF [1] ?

If so, please let me know the keywords,

thanks,
Alex.

ADDED:

because, as far as I understand excited-state finite lifetime [2] calculations could be run using this input:

...

property
 response 1 8.8559E-2
 damping 0.007
end

raman
 resonance
end

task dft raman


it the latter case, I think, numerical derivatives of the gradients (2nd derivatives of energy) are computed.

Hi, Yes. This can be done. I recommend using the 6.1.1 version which you can download from the download link of the NWChem webpage.

Check the properties section in the manual for the keywords relevant to this:

Let me know if there are any issues.
