## Abstract In order to investigate the phase transition in terms of lattice dynamics, the symmetry modes of the paraβ and ferroelectric phases of the semiconductor SbSI are analysed by means of group theory. Starting from the simplified C^2^~2h~ space group with two formula units per unit cell, th
