The comparatively higher HOMOeLUMO gap for N1 and N2 is possibly due to their similar molecular structure with respect to the presence of an aromatic indole moiety in both the dyes. Values of ground state dipole moment (m0) for N1, N2 an ...

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.
