Surface Phonons in Molecular Crystals

Abstract

The lattice dynamics of the surface layers of anthracene and β‐paradichlorobenzene crystals as well as of the adsorbed monolayer of paradibromobenzene on β‐paradichlorobenzene is investigated using the method of atom—atom potentials in slab dynamical calculations. The dynamic, structural, and electro‐optical parameters of the surface crystal layers are compared with those for the bulk.
