Re: Negative nuclei repulsion energies in DPCM energy calculation

Alex Granovsky

Dear Tatiana,

actually, this is redefined nuclear repulsion term, namely,
the repulsion of bare nuclei plus PCM's interaction of nuclei
with polarization charges caused by nuclei. It can be either  
positive or negative, there are no restrictions.

Kind regards,
Alex Granovsky
