✦ Synopsis

We report on the firsr obxrvaGon of the csciples fluorssccnce via van dzr Waals complex lbrmation of l-cyanonaphthalcnc and triethyhminc in a supersonic molecular bcarn. The formarion of van der Waals complex is evidenced to play an important role in the esciples formation. The cffecl of escitation energy on the esciples formation is also reported.

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
