Abstract

The frequencies of A2u phonons of the layer compounds ZrS2 and HfS2 are determined from two phonon resonant Raman scattering. The analysis based on the polarizable ion model by van der Valk and Haas suggests that the long-range Coulomb interaction plays an important role in the anisotropy of lattice dynamics. The Alg phonon spectrum of ZrS2 exhibits anomalous line shape induced by the hybridization of the Alg phonon with the A2u(LO).
