用化学激光技术测定了氯乙烯（CH 2 =CHCl，CH 2 =CDCl，CH 2 = CCl 2，cis-和trans-CHCl =CHCl，CHCl= CCl 2）在λ ≥ 1550 A下光解的相对光化学产物产率和HCl <$（v′ ≤4）光消除产物的电子振动态分布。所观察到的高度非统计的产品电子振动态分布成功地匹配的自举反应动力学模型，该模型考虑了突然的结构扭曲和分子内松弛的盐酸，因为它从乙炔或卤代乙炔产品分离。还报道了氯乙烯的真空紫外吸收光谱（λ≥ 1400）。所有可用的光谱，光化学，和产品的能量分配数据被用来制定一个状态到状态的光化学反应机制，从氯乙烯的HCl光消除。
Chemical laser techniques have been used to determine relative photochemical product yields and HCl† (v′ ≤4) photoelimination product vibronic state distributions resulting from chloroethylene (CH2=CHCl, CH2=CDCl, CH2=CCl2, cis‐ and trans‐CHCl=CHCl, and CHCl=CCl2) photolyses at λ ≥ 1550 A. The observed highly nonstatistical 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 haloacetylene products. Chloroethylene vacuum ultraviolet absorption spectra (λ≥ 1400 A) 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.
