โœฆ Synopsis

A review of the lattice dynamics of gases adsorbed on graphite in the commensurate phase is presented, taking into account their quantum character. The phonon dispersion curves are characterized by an energy gap in the acoustic branch at the zone center, Its magnitude is related to the corrugation of the in-plane adsorption potential. The energy of the zone boundary phonons, on the other hand, is determined by the interaction between adatoms. The measurement of these quantities allows the comparison with theoretical models.

X-ray dIffraction is used to confirm that benzene forms a fi X fi commensurate overlayer upon the basal planes of graphite. This result agrees with previous neutron diffraction studies and does not agree wth recent theoretical calculations. The reasons for this are discussed.
