dc.description.abstract	The phonon dispersion relations of diamond-like crystal structures are studied by using a Born-von Kannan model with interatomic interactions up to and including second neighbours. Analytical expressions for dispersion relations in the principal symmetry directions are derived. The force constants of grey tin are determined by an optimization procedure using the dispersion data in the [00k], [kk0] and [kkk] directions. The dispersion curves calculated with a two-neighbour six-parameter Bora-von Kannan model give a reasonable fit to the dispersion data in the principal symmetry directions.
