Abstract

Some universal characteristics are discussed of the decay lifetimes and fluorescence quantum yields from the S1 manifold of large molecules, which originate from the coupling between intrastate vibrational energy redistribution and interstate electronic relaxation. The time-resolved total fluorescence decay from the S1 state of jet-cooled 9-cyanoanthracene exhibits non-exponential decay in the energy range Ev= 1200-1740 cm-1 above the S1 origin, which does not originate from dephasing but rather manifests the effects of intrastate intermediate level structure for vibrational energy redistribution on intersystem crossing.
