WebDec 2, 2024 · 7.8: Rotational Spectra of Polyatomic Molecules. The Franck-Condon Principle describes the intensities of vibronic transitions, or the absorption or emission of a photon. It states that when a molecule is undergoing an electronic transition, such as ionization, the nuclear configuration of the molecule experiences no significant change. WebFranck–Condon configuration diagram and absorption spectrum for a diatomic molecule. In the absorption curves, the dashed curve is for molecules in solution and the solid lines are for molecules in vapor form. E A is the absorption at the Franck–Condon maximum, and E B is the emission at the Franck–Condon minimum; r is the nuclear separation.
