Birge–Sponer method

The Birge–Sponer method is a technique used in molecular spectroscopy and quantum chemistry to determine the dissociation energy of diatomic molecules. The method relies on analyzing vibrational energy levels, particularly the transition energies between vibrational states of a molecule. ### Key Concepts of the Birge–Sponer Method: 1. **Vibrational Energy Levels**: Diatomic molecules exhibit quantized vibrational states that can be described by quantum mechanics.
