Abstract
The vibrational modes of antimony sulphur iodide (SbST) crystals are d etermined in the para electric and ferroelectric crystalline phases by using the correlation method. The number of normal modes of a crystal which vibrate, are found using the full symmetries of the irreducible representation of the relevant crystallographic point group. The ferr oic state of the Crystal SbSI is associated with the irreducible repre sentation of the underlying point group.
