This approximation allows us to:
1. Construct energy level diagrams like:
2. Total energy of a molecular state is the sum of:
3. Total wavefunction is the product of wavefunctions for the electrons and nuclei with vibrational and rotational parts.
4. Nuclei remain fixed during much faster electronic transition - transitions are vertical.
