Abstract
The dependence of force constants (ν 2μ) on equilibrium interatomic distances are analysed for the following three diamond-like crystal groups: IV–IV, III–V and II–VI. We have considered the models due to Varshni and Anderson and arrived at a simpler relation. It is found that the force constants are presented as a function of interatomic distances within an accuracy of ≈ 3%. The model constants are evaluated by least-squares fitting of available experimental data, and the parameters, along with the relative merits of the models, are presented.
