Hi

these features are not available with DFTB in CP2K.

regards

Subject: [CP2K:17801] Raman and IR spectra using DFTB in CP2K for periodic systems

Dear all,

I would like to calculate the Raman activities / IR intensities and in turn the Raman-IR spectra of several periodic systems with DFTB. I was wondering if CP2K has such an implementation and if not if it is at least possible to get the cartesian polarization and polarizability tensor out from a DFTB calculation for a periodic system in CP2K.

Thank you in advance.

Sincerely yours,

Ariadni
