Dear AMBER community,
I have some questions on charge derivation. Does it matter for RESP charge
fitting of QM ESP that intramolecular H-bonds are present in the molecule? I
know that for AM1 derived charges these H-bonds must be avoided.
What influence does it make whether these bonds are present/absent from the
crystal structure/MD? What
change is there for this case in using B3LYP derivation scheme for
polarizable FF?
Who could say anything relavant to this is warmly welcome.
Thanks for your replies.
Regards,
Martin Lepsik
