From the study of triplet exciton trapping in 1,4-dibromonaphthalene, it appears that several optically accessible excitons can exist with excitation energies within 1 cm-1 and lifetimes differing by 2 orders of magnitude. Furthermore trap-like states exist ~2 cm-1 below the exciton band. Delayed fluorescence arises from annihilation between an exciton and the very shallow trap-like state.
