An investigation of transient absorptions and a streak camera study of the fluorescence generated by UV excitation of hexafluorobenzene

The decay of the fluorescence at 360 nm of hexafluorobenzene in the vapour phase and in liquid solutions has been studied with a carefully corrected and calibrated streak camera. The fluorescence is emitted by short living (S s) and long living (S l) species which are formed from the primary excited...

Description
Summary:The decay of the fluorescence at 360 nm of hexafluorobenzene in the vapour phase and in liquid solutions has been studied with a carefully corrected and calibrated streak camera. The fluorescence is emitted by short living (S s) and long living (S l) species which are formed from the primary excited state S p. The previous results from a streak-camera study are not reproduced. Transient absorptions at 600 nm reveal that a precursor of the Dewar isomer and an as yet unidentified species are also formed directly from S p.
