Abstract
Hartree–Fock self-consistent field calculations on the 3-21G(*) level of approximation have been performed to phosphorylcholine and its derivatives in a geometry close to an X-ray structure of an antibody/antigen complex. Wave functions have been analyzed using different methods for derivation of atomic charges used as Coulomb charges in empirical force fields for molecular dynamics simulations. Among the three applied methods—Mulliken population analysis, natural population analysis, and electrostatical fit—the natural population analysis seems to give best results for these molecules.
