โœฆ Synopsis

The resonanceenhanced ionization spectrum of a trimethylcyclohexene compound in which the cyclohexene ring is formally conjugated to a phenylbutadienyl system has been recorded in a supersonic jet expansion. Two strong origin transitions, associated with different ground-state conformers, were identified, indicating that the electronic transition occurs with little change in torsional geometry. The frequencies at which these origin transitions occur indicate that the torsional angle between the cyclohexene double bond and the phenylbutadienyl system is 15 a from perpendicular. Similar electronic and steric forces are expected to govern the ground-state torsional geometry of the p-ionylidene ring in retinal.

The T,-To electronic spectrum of jet-cooled phenyl nitrene has been examined by the LIF technique for the first time. The observed spectrum is ascribed to phenyl nitrene, which could be obtained by an excimer laser photolysis of two different precursors. The system origin has been determined to be l

Free radicals are produced by excimer laser flash photolysis of a suitable precursor inside the nozzle of a pulsed slit jet and cooled by supersonic expansion from the slit. The infrared spectra of the radicals are then probed by a single-frequency colorcenter laser. This technique has been tested o

We obtain dispersed fluorescence (DF) spectra of jet-cooled DCO from three excited-state levels in the 13 2/~\_~ 2/( system. These spectra yield term energies and relative fluorescence intensities for 112 levels (mostly quasibound resonances) of DCO ()0 over an energy range of 0-19000 cm 1. We make
