... Note that increasing n corresponds to tan increasing electron orbital radius (in the Bohr model). As n approaches ∞ (r approaches ∞) , the energy approaches the ionization energy of hydrogen. We see that for n = 1, we have l =0, m=0, s=±1/2, so that there are two (2) possible combinations of quantum ...

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.
