✦ Synopsis

The fluorescence excitation spectra of the 1: 1 complexes of indole with DsO in a cold ( z 1 K) expansion jet are reported and compared with those of the Hz0 complexes. For the more red-shifted complex, the small isotope effect and the long Franck-Condon progression in the 35 cm-' intermolecular vibration can be lit to a 0.42f0.04 A displacement of the entire water molecule upon excitation. In spite of the large displacement and red-shift, the emitting state for this complex is assigned iI+ on the basis of simulated fluorescence curves.

The fluorescence excitation spectrum of [2.2]paracyclophane has been recorded from 30675 to 32570 cm-'. Two inter-ring vibrations, the breathing mode and the twisting mode, are responsible for the extensive vibronic structure in this lowest-lying electronic transition. The breathing mode gives rise

The lowest excited singlet site of 9,10-dihydroanthracene has been studied by supersonic-jet laser spectroscopy. The spectrum consists of a number of prominent low-frequency vibronic bands near the O-O band followed by a structureless continuum. The low-frequency vibronic bands are nicely fitted wit

The laser-induced fluorescence spectrum of gas-phase PHI cooled in a supersonic jet has been observed in the range 490-550 nm. A rotational analysis was carried out for the (0, 0, 0)-(0, 0, 0), (0, 1, 0)-(0, 0,O) and (0,2,0)-(O, O, 0) bands of the A 'A,-X ZBI electronic transition of PHr. About 220
