Abstract Calculations of the phonon spectrum of crystalline In4Se3 in a model of central-pair interactions with neglect of the long-range forces are presented. The model developed contains five unknown parameters, which are determined from experimental values of the elastic moduli without consideration of the internal displacement of the sublattices. The phonon spectrum obtained contains a large number of low-frequency modes, which deform the acoustic branches. Some common features are discovered in the dispersion curves of the electron and phonon spectra.
