Abstract
Energy dependence of luminescence from quinoline and isoquinoline vapors indicates that S1→S0 internal conversion, already important at zero excess vibrational energy, becomes the dominant photophysical process with vibrational excitation of the molecule in S1. This is predicted to be a general phenomenon for molecules with closely spaced, lowest energy, nπ* and ππ* singlet states.Keywords
