The Chloroethylene Photochemical Lasers: Vibrational Energy Content of the HCl Molecular Elimination Products.
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.
