... Here, Wmn are the rates of interstate transitions; anm ≡ hn|a|mi. We disregard tunneling when defining functions |ni ≡ ψn (Q), i.e. we use the wave functions localized about the extrema of g(Q, P); the effect of tunneling is exponentially small for λ 1 and |n − m| λ−1 . We count the localized st ...

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.
