Paper Abstract

The kinetics of the photochemical ring openings of 1,3-cyclohexadiene (CHD), 1,3,5- cyclooctatriene (COT) and ((alpha) -PHE) were determined by picosecond, time-resolved UV resonance Raman spectroscopy. The time evolution of the photoproduct ethylenic intensity demonstrates that the photolysis of CHD produces ground state cis-hexatriene in 8 +/- 1 ps. Similarly, the photoproducts of COT and (alpha) -PHE appear in 12 +/- 2 ps and 11 +/- 2 ps, respectively. The similar ground state photoproduct formation times of these reactions indicates that the $OM10 ps timescale is a general feature of photochemical electrocyclic ring-opening reactions.
