Abstract

Values of the coefficients C3 and C5 which describe the asymptotic potential energy between an atom or molecule and a surface, and the constants Cs1 and Cs2 which characterize the surface mediation of the long-range atom(molecule)-atom(molecule) interaction, are calculated for rare gas and alkali or simple molecules, such as NO, H2, and H2O, adsorbed on noble and transition metals. These calculated results are obtained using analytic representations of the atomic polarizability and a numerical treatment of the substrate dielectric response obtained from measured optical constants.
