[CP2K-user] [CP2K:16707] obtaining atomic polar tensor or effective born charges in vibrational calculations

[Jürg Hutter]

Hi

Born charges are not implemented in CP2K.
You could calculate them, e.g. by finite differences of polarizabilities along atomic coordinates,
or finite differences of atomic forces along applied electrical fields.

regards

Subject: [CP2K:16707] obtaining atomic polar tensor or effective born charges in vibrational calculations

Hi all,

I am running vibrational calculations and want to obtain the atomic polar tensors (some times also called the born charges). How can one do this within cp2k? I tried setting the print level to high, but it is not printed in the output file or any of the other files. Can someone help me with this?

Kind regards,
Roel v/d Ven
