Character Table



Character table are used within inorganic molecular spectroscopy to calculate infrared (IR) and Raman molecular rotations. In addition, character tables are used to work out molecular orbitals and molecular microwave vibrations.

There are a range of character tables for the point groups. These are used for calculating which molecular rotation is Infrared or Raman active. Information on how to use these is here.
