Vacuum ultraviolet laser‐induced fluorescence kinetic study of the reactions of Cl atoms with fluoroalkenes (C x F 2x+1 CHCH 2 , x = 1,2,4, 6, and 8) at low pressures

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.
