Abstract

Group theory is a technique which helps spectroscopists to establish theoretical calculation in vibrational frequencies of a molecule. Vibrational frequencies of a molecule can be determined by Infra red and Raman spectroscopy. In this article, different symmetry elements in group theory has been discussed. Point groups have also been discussed. Using the symmetry elements determination of dipole moments of molecule, and optical activity of molecule have been done.

Keywords: Dipole Moment, Optical Activity, Point Group, Symmetry Element
