摘要：

The vibrational spectrum and one-phonon density of states of a chalcopyrite crystal AgGaS2 are calculated in an extended Keating's model with two-bond-stretching and one-bond-bending force constants. Three charges of ions and three force constants are determined by a least-square fitting to experimental frequencies of long-wave phonons taken from Raman-scattering experiments. The calculated constant-volume specific heat, Debye temperature and elastic constants, of AgGaS2 are in agreement with the experimental data of other authors.
