Quantum Chemistry 12.15 – Irrep Direct Products

Short lecture on irrep direct products.

The irreducible representations of a point group form a group themeselves through their multiplication. This is relevant in molecular term symbols, where the direct product of all molecular orbital irrep labels results in the irrep of the total wavefunction, for example singlet A1 as the ground state of H2O.
