Abstract
Pulsed laser photolysis/vacuum ultraviolet laser‐induced fluorescence techniques were used to measure rate coefficients for Cl atom reactions with a series of fluoroalkenes (C~x~F~2x+1~CHCH~2~, x = 1,2,4,6,8) in 6–10 Torr of CF~4~ diluent at 295 ± 2 K. Rate coefficients (units of 10^−11^ cm^3^ molecule^−1^s^−1^) of 4.49 ± 0.64, 6.58 ± 0.59, 8.91 ± 0.58, 9.27 ± 0.64, and 9.00 ± 0.87 were determined for C~x~F~2x+1~CHCH~2~ with x = 1,2,4,6, and 8, respectively. In 6–10 Torr of CF~4~ diluent, the kinetics of the title reactions are at, or near, the high‐pressure limit for x = 4, 6, and 8, approximately 30% below the high‐pressure limit for x = 2, and approximately 50% below the high‐pressure limit for x = 1. © 2007 Wiley Periodicals, Inc.
