Fluorescence from jet-cooled adduets of styrene and aliphatic amines is reported. Exciplex-type emission is observed from styrene: tertiary amine adduets, as in previous solution work, and from styrene: secondary amines for the first time. The exciplexes are characterized by much longer decay times
Van der Waals complexes composed of naphthalene and triethylamine have been studied in free jet expansions by fluorescence excitation and resonance-enhanced two-photon ionization techniques. Intermolecular vibrational bands with frequencies of 8 and 40 cm-' appear to promote exciplex formation. The
Molecular exciplex formation under supersonic jet conditions is studied as a transition from the excited state of the van der Waals complex to a charge-transfer state. For a typical model exciplex system the role of excess excitation energy in the formation process is investigated.
