Dynamics and spectroscopy of hydrogen atoms on Pd{111}
Article Abstract:
Chemisorption of hydrogen on Pd{111} is a relatively simple, surface chemical process, by using low-temperature scanning tunneling microscopy, tip-induced motion of absorbed atomic hydrogen at 4K is observed at low coverage. The motion is ascribed to excitation of vibrational modes that decay into translational modes, while vibrational spectroscopy through inelastic electron tunneling corroborates this assignment, and the barrier to hydrogen atom motion is determined.

Theoretical study of CO and NO chemisorption on RhCu(111) surfaces
Article Abstract:
A systematic density functional theory study using periodic models is presented concerning the chemisorption of CO and NO on various sites of RhCu(111) surfaces. It is suggested that it is possible to control the adsorption sites of the molecules by appropriate choice of the surface composition.
