The phonon dispersion relations in a CsH₂PO₄ crystal in a paraelectric phase by means of a rigid molecular-ion model are calculated. The phonon spectra in the quasi-harmonic approximation at various values of temperature and hydrostatic pressure are obtained. The condensation of Au external phonon...
