The proton transfer energy curve for the hydrogen fluoride-ammonia system was studied by semi-empirical methods in vacuo and in a hydrated form. It was found that the simple point-charge approximation cannot be used to estimate the Coulombic interaction term rather the molecular electrostatic potential has to be considered. Furthermore, even inclusion of the mutual polarization term is insufficient if quantitative agreement with CNDO/2 supermolecule results is desired since charge transfer plays an important role.
