    Abstract

    The technique of laser flash phyotolysis/laser absorption has been used to obtain absolute removal rate constants for singlet methylene, 1CH2 ( a ̃1A1), with various saturated and unsaturated hydrocarbons. The removal rate constants for CH4, C2H6, C3H8, C2H4, C3H6, C2H2, CH2CCH2, and C6H6 were found to be in excellent agreement with previously reported results. Removal rate constants were also measured for n-C4H10, i-C4H10, n-C5H12, c-C3H6, c-C6H12, 1-C4H8, cis-2-C4H8, trans-2-C4H8, and 1-C4H6, and determined to be (3.17 ± 0.15), (2.53 ± 0.11), (3.35 ± 0.24), (1.63 ± 0.08), (3.77 ± 0.21), (3.80 ± 0.20), (3.67 ± 0.16), (3.43 ± 0.16) and (4.05 ± 0.18) × 10-10 cm3 molecule-1 s-1, respectively. This series of hydrocarbons forms the basis of a larger series of compounds containing a wide variety of organic functional groups. The removal rate constants are reported here, both as a series within its own right, and as a reference point for future work.
