摘要：

The low frequency surface phonon dispersion curves have been determined for clean Rh(111) and ordered monolayers of CO and benzene on this surface using inelastic He-atom scattering. In addition the low-frequency external vibrations of the chemisorbed CO and benzene molecules were observed. As in case of the chemisorbed benzene this energy regime has not been investigated, previously extended Hueckel calculations were used to identify the observed mode as the frustrated translation of the benzene molecule parallel to the surface.
