): A rotation followed by a reflection through a perpendicular plane. 2. Point Groups
A vibration must change polarizability (matches quadratic terms like Symmetry & Group Theory in Chemistry
are the mathematical tools chemists use to describe and predict the behavior of molecules based on their shape . By categorizing a molecule’s symmetry, we can simplify complex quantum mechanical problems, predict spectroscopy results, and understand bonding. 1. Symmetry Elements and Operations ): A rotation followed by a reflection through
