Time-resolved fluorescence measurements have been made of the predissociation of van der Waals complexes of perylene with Ar and CH4. At 705 cm-1, predissociation of Ar1,2complexes occurs in competition with efficient singlet-triplet coupling. At 900 cm-1, both Ar and CH4complexes show little contribution from singlet-triplet coupling. The predissociation of CH4complexes at this energy is very rapid, largely as a result of extensive vibrational coupling. © 1989.
