Lattice vibrations of molecular solids

More recently, interest in the lattice vibrations of molecular solids has centered around the elucidation of intermolecular potential functions. If a pair potential is assumed, it can be tested by calculating the observables by application of the appropriate lattice dynamics. Dows (1962) was the first to attempt a calculation of lattice vibrational frequencies from an assumed potential. He treated solid ethylene and used a model which represented the pair interaction by repulsions between hydrogen atoms on neighboring molecules. [Pg.207]

The lattice vibrations of molecular solids have received brief consideration in reviews dealing with the infrared spectra of these solids (Dows, 1963,1965, 1966). ThereviewbySchnepp (1969) provides a good summary of the field. A recent review by Venkataraman and Sahni (1970) of the lattice dynamics of complex crystals contains much subject matter related to the present review. A number of good reviews are available on the lattice motions of ionic, covalent, and metallic solids (Mitra and Gielisse, 1964 Martin, 1965 Cochran and Cowley, 1969). [Pg.208]
