Vibrational Spectrum using Polarizable Continuum Model

I want to find which file implemented the contribution of PCM to dipole operator for vibrational spectrum like IR. Is someone familiar with that?
Thanks in advance.

Hi @zheng, analytical first and second nuclear derivatives are currently not implemented with PCM.

Ok, thanks for your reply.

Any concrete plans to implement first derivatives of PCM at least for HF/DFT?
