The photolysis of cis-1,2-dichloroethylene has been investigated in the presence of I2 as a function of incident wavelength and as a function of initial cis pressure. The results indicate that at ± 〉 2200Å the following primary processes occur: \documentclass{article}\pagestyle{empty}\begin{document}$$ cis{\rm - 1,}2{\rm - C}_{\rm 2} {\rm H}_{\rm 2} {\rm Cl}_{\rm 2}^ * \to {\rm C}_{\rm 2} {\rm H}_{\rm 2} + {\rm Cl}_{\rm 2} $$\end{document} \documentclass{article}\pagestyle{empty}\begin{document}$$ cis{\rm - 1,2 - C}_{\rm 2} {\rm H}_{\rm 2} {\rm Cl}_{\rm 2}^ * \to {\rm C}_{\rm 2} {\rm HCl} + {\rm HCl} $$\end{document} \documentclass{article}\pagestyle{empty}\begin{document}$$ cis{\rm - 1,}2{\rm - C}_{\rm 2} {\rm H}_{\rm 2} {\rm Cl}_{\rm 2}^ * \to {\rm C}_{\rm 2} {\rm H}_{\rm 2} {\rm Cl} + {\rm Cl} $$\end{document} The lifetime of the excited state yielding the above products is estimated at about 2.4×10-9 sec. At shorter wavelengths additional C2H2 is produced by decomposition of a vibrationally excited C2H2Cl radical.Scavenging of the CHClCH radical by I2 produced trans and cis-CHClCHl in a ratio of 4 to 1, respectively.
