In the parameter files of the gaff force field you have atomtypes like
 "H bonded to aliphatic carbon with 1 electrwd. group"
Can anyone please enumerate the electron withdrawing groups that we are
dealing with here??
Also does one find Sp2 N with three connected atoms commonly in strucuture
files of small molecules. Or does such a case arise only when we explicitly
protonate a Sp2 N with two connected atoms.
Regards
Sankha
