Abstract

In this work we present the results of theoretical calculations of phonon spectra of Tl4HgI6 crystal. Based on grouptheory analysis the symmetry classification of phonon modes carried out. Moreover the distribution of vibrations for symmetry classes of single crystals and the selection rules for vibrations in the IR- and Raman spectra are obtained

Keywords: lattice, grouptheoryanalysis, basis, phononspectra
