Ionization of a molecule by photoionization or by energetic electrons (sometimes called "electron impact") is governed by the Franck-Condon principle, which states that the most probable ionizing transition will be that in which the positions and momenta of the nuclei are unchanged. Thus, when the equilibrium ...

Web1. The fact that the fluorescence wavelength is often much longer than the irradiation wavelength (Stokes shift) is a consequence of which phenomenon? a) low extinction coefficients (Lambert-Beer law) b) vertical transitions (Kasha’s rule) c) high ISC rates (El Sayed rule) d) the Franck–Condon principle View Answer 2. WebThese explanations were not supported by the first principle simulations until now.
