Partial Charges



 Dear CCl'ers-
 I have been calculating spin densities and partial charges
 in the presence of a backgound charge distribution using the CHARGE
 keyword in G94.  I'm using the charge distribution to simulate charges in
 a protein environment, however, I don't know how the external point
 charges are included in the Hamiltonian.  The reference given
 in the G94 manual only discusses how the spherical Gaussian density
 basis functions are implemented, not the point charges.
 Can anyone direct me towards a reference(s) on how this is done??
 I'll post a summary of responses...
