Abstract

Absolute rate constants for the reaction of S(^3^P) with ethylene episulfide were measured over a C~2~H~4~S concentration range of 5, a total pressure of 20–200 tort, and a flash intensity range of ˜4. Over this range of variables, the bimolecular rate constant was found to be invariant. Because of limitations imposed by the physical properties of the reactant C~2~H~4~S, temperature variations were necessarily held to the range 298–355°K. The bimolecular rate constant was found to be invariant over this limited temperature range, having a value of (4.47 ± 0.26) × 10^−11^ cm^3^ molec.^−1^ sec^−1^. The possible influence of this reaction in studies of the S(^3^P)–ethylene system are discussed.
