Symmetry gives us a sense of beauty and group theory is the study of symmetry in molecules mathematically. The book covers the essential basics of group theory. The book presents a fascinating journey through the basic concepts of symmetry with symmetry elements in molecules various operations point groups matrix representations and the construction of character tables. It also presents a detailed and clear view of some chemical applications of group theory like a workout on molecular vibrational modes hybridization group theoretical calculations and symmetry selection rules for electronic infrared and Raman transitions.
