You could follow what has been done by:
P. Cieplak, W.D. Cornell, C.I. Bayly & P.A. Kollman J. Comput. Chem. 1995, 16,
1357-1377.
See also the RED FAQ
http://www.u-picardie.fr/labo/lbpd/RED/FAQ-I.htm
You could also use CH3CO-NHCHRCOOH and get the RESP charges using
intra-molecular restraints for CH3CO = 0.
This is automatically done in R.E.D.-III. We hope to release it sometime
beginning of next year...
