[DFTB-Plus-User] Raman Intensities

[Amritpal ghumman]

Hi..

I have performed second derivatives to calculate hessian, born and
bornderiv. Then I performed modes calculations using hessian, born and
bornderiv.

In output of the modes calculation, there are Vibration frequencies and
corresponding polarizability changes. How can we get raman intensities from
these polrizability changes?

With Best Regards
