Quantum Chemistry and Spectroscopy - Quantum Chemistry 12.16 - Symmetry IR / Raman Activity

Short lecture on the IR and/or Raman activity of vibrational modes. The vibrational normal modes of molecules belong to one of the irreducible representations of the molecular point group. By removing the translational and rotational components from the reducible representation of the coordinates of the atoms. IR active modes belong to linear irreps, and Raman active modes belong to quadratic irreps.
