Abstract:

Chemical laser techniques have been used to determine relative photochemical product yields and HCl v or 4 photoelimination product vibronic state distributions resulting from chloroethylene CH2 CHCl, CH2 CDCl, CH2 CCl2, cis-and trans-CHCl CHCl, and CHCl CCl2 photolyses. The observed highly non-statistical product vibronic state distributions are successfully matched by a bootstrap reaction dynamics model which considers sudden structural distortion and intramolecular relaxation of HCl as it separates from acetylene or halocetylene products. Chloroethylene vacuum ultraviolet absorption spectra are also reported. All available spectroscopic, photochemical, and product energy partitioning data are used to formulate a state-to-state photochemical reaction mechanism for HCl photoelimination from the chloroethylenes.
