The reaction of chlorine atoms with ethylene and two of its deuterium isotopomers in solid para-hydrogen (p-H2) matrices at 3 K has been studied using infrared spectroscopy. Irradiation at 365 nm of a co-deposited mixture of Cl2, C2H4, and p-H2 at 3 K produces a series of new lines in the infrared spectrum. Several of the new lines are readily assigned to the gauche and trans conformers of 1,2-dichloroethane (CH2ClCH2Cl) resulting from the addition of two Cl atoms to C2H4. Of the remaining lines, a strong line at 664 Cm-1 and three weaker lines at 562, 1070, and 1228 Cm-1 are concluded to be due to a single carrier based on their behavior upon subsequent annealing to 4.5 K and irradiation at 254 and 214 nm. When the positions and intensities of these lines are compared to the MP2/aug-cc-pVDZ predicted vibrational spectra of the possible species that could result from the addition and abstraction reactions of one Cl atom with C2H4, the best agreement is found with the 2-chloroethyl radical (CdotCH2CH2Cl). In order to confirm this assignment, isotopic experiments were performed with C2D4 and t-C2H2D2 and the corresponding infrared bands due to the deuterium isotopomers of this radical (CdotCD2CD2Cl and \cdotCHDCHDCl) have been observed. A final set of experiments were performed following irradiation of the Cl2/C2H4/p-H2 mixture at 365 nm, in which the matrix was irradiated with filtered infrared light from a globar source, which has been shown to induce a reaction between isolated Cl atoms and matrix H2 to produce HCl and H atoms. In our experiments, the major products observed were HCl and ethyl chloride (CH3CH2Cl) and the possible mechanism of the formation of ethyl chloride will be discussed.
