VIBRATE! A program to compute irreducible representations for atomic vibrations in crystals

VIBRATE! is a computer program that uses group theory to carry out factor group analysis of a crystal structure. The symmetry species of the normal modes of vibration are derived, together with information relating to the symmetry-adapted vectors. The program is simple to use, relying on input mainly from a crystallographic information file. The output is presented in a form that should be familiar not only to crystallographers but also to others such as chemical spectroscopists.
