Abstract

We have calculated the interaction potentials of H₂, D₂ and Ar with the basal plane of graphite. The repulsive part of the potential is constructed using the "effective medium theory" (EMT), while the attraction consists of anisotropic damped dipole and quadrupole terms. The diffusion coefficient for single H₂ and D₂ molecules adsorbed on graphite has been evaluated. We also present the coefficient for the long range interaction for an atom or molecule with a rare-gas plated graphite surface.
