Surface Dynamics of Molecular Crystals. A Calculation for Naphthalene

Abstract: A model for calculating the statics and dynamics of a surface of a molecular crystal is presented.The (001) surface of naphthalene is chosen. The potential function used is the 6-exp non-bonded atom-atom function, which has gained success in lattice dynamics. Surface layers of different thicknesses are investigated, all indicating that the third layer deep has a maximum binding energy. A slab of twelve layers thickness is used for the dynamics calculation, which shows clear evidence of surface modes. These are… Show more

“…Besides it, the qualitatively new effect due t o the lattice discreteness is the appearance of purely transverse SV on nonpolar crystals [2,3]. The surface optical vibrations in molecular crystals were studied in [4]. Up to now the surface optical phonons were observed to appear in infrared absorption and Raman scattering spectra for a large enough number of samples.…”
