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.
