bool OEMMFF94PartialCharges(OEMolBase &mol)
Assigns MMFF94 partial charges. Requires a prior call of OEMMFFAtomTypes. Charge 0.0 is assigned to any atom missing proper MMFF94 atom type. Returns true when charges are successfully assigned.
This function assigns silently zero charges to all atoms if MMFF94 atom types are not assigned to the passed molecule.
