摘要：
A critical analysis of existing experimental and theoretical information on the lattice dynamics of the layered crystal α-HgI2 is performed. It is shown that a satisfactory understanding of the character of the interatomic interaction and characteristic features of the phonon spectrum of this material can be obtained in a simple phenomenological model with eight parameters, assuming that Eg/B1g degeneracy of the 29 cm−1 Raman line is of a two-phonon nature.
