Abstract

The vibrational symmetry decomposition have been received using the method of classification vibrational modes in superspace approach. Decomposition of the full vibrational representation of the investigated crystal Hg3Te2Cl2 and its decompositions after irreducible representations for each atom of a crystalline lattice have been obtained.
