... 1. Compute U/(RT) of a mole of diatomic ideal gas molecules treating the vibrational mode classically. Assume that the vibrational frequency is 1013 s-1, and take the reference state as E = 0 when the system is in its ground state (degeneracy of 1 and no important excited electronic states). In a fe ...

Franck–Condon principle
The Franck–Condon principle is a rule in spectroscopy and quantum chemistry that explains the intensity of vibronic transitions. Vibronic transitions are the simultaneous changes in electronic and vibrational energy levels of a molecule due to the absorption or emission of a photon of the appropriate energy. The principle states that during an electronic transition, a change from one vibrational energy level to another will be more likely to happen if the two vibrational wave functions overlap more significantly.
