Quantum treatment of H adsorbed on a Pt(111) surface -: art. no. 033406

A static potential energy surface for 1/4 of a monolayer of adsorbed hydrogen atoms on a Pt(111) surface has been calculated using first-principles density-functional theory calculations. The Schrodinger equation is solved for the hydrogen atoms in this potential. The results agree well with stable site, vibrational spectroscopy, and diffusion measurements, and resolve the conflicting interpretations of those experiments.
