Actually I found the partial charges on amino acid residues, RNA, nucleic
acids etc in papers, and also as you said, in .lib files, but I could not
find the partial charges in some organic molecules, for example, the
nitrile group (-CN) I asked on the list a few days ago. Do you have any
suggestion about that? thanks again.
