Abstract
Rate coefficients, k, and ClO radical product yields, Y, for the gas-phase reaction of O( 1D) with CClF 2CCl 2F (CFC-113) (k 2), CCl 3CF 3 (CFC-113a) (k 3), CClF 2CClF 2 (CFC-114) (k 4), and CCl 2FCF 3 (CFC-114a) (k 5) at 296 K are reported. Rate coefficients for the loss of O( 1D) were measured using a competitive reaction technique, with n-butane (n-C 4H 10) as the reference reactant, employing pulsed laser photolysis production of O( 1D) combined with laser-induced fluorescence detection of the OH radical temporal profile. Rate coefficients were measured to be k 2 = (2.33 ± 0.40) × 10 -10 cm 3 molecule -1 s -1, k 3 = (2.61 ± 0.40) × 10 -10 cm 3 molecule -1 s -1, k 4 = (1.42 ± 0.25) × 10 -10 cm 3 molecule -1 s -1, and k 5 = (1.62 ± 0.30) × 10 -10 cm 3 molecule -1 s -1. ClO radical product yields for reactions (2)-(5) were measured using pulsed laser photolysis combined with cavity ring-down spectroscopy to be 0.80 ± 0.10, 0.79 ± 0.10, 0.85 ± 0.12, and 0.79 ± 0.10, respectively. The quoted errors in k and Y are at the 2σ (95% confidence) level and include estimated systematic errors. © 2011 Wiley Periodicals, Inc.
