Abstract

Within a model of central and noncentral forces the exact change of the vibrational entropy, ΔS, is calculated, both as function of the degree of order and as a function of the diverse force constants. A linear relationship between ΔS and the short-range order parameter is found. Results of ΔS as a function of the force constants are compared with ΔS as calculated by an empirical formula based on a modified Einstein crystal model.
