Abstract

Simple formula for microscopical estimation of the Debye temperature for polyatomic crystals is reported. It is based on the calculation of the force constants for arbitrary pair of interacting atoms by means of the phenomenological spectroscopy data for oscillation frequencies of homonuclear molecules. For that purporse a special combinative rule is suggested. The table of necessary parameters for calculation of Debye temperatures of arbitrary crystals and solid solutions is included.
