The pulsed laser photolysis‐resonance fluorescence technique has been used to determine the absolute rate coefficient for the Cl atom reaction with a series of ketones, at room temperature (298 ± 2) K and in the pressure range 15–60 Torr. The rate coefficients obtained (in units of cm 3 molecule −1 s −1 ) are: acetone (3.06 ± 0.38) × 10 −12 , 2‐butanone (3.24 ± 0.38) × 10 −11 , 3‐methyl‐2‐butanone (7.02 ± 0.89) × 10 −11 , 4‐methyl‐2‐pentanone (9.72 ± 1.2) × 10 −11 , 5‐methyl‐2‐hexanone (1.06 ± 0.14) × 10 −10 , chloroacetone (3.50 ± 0.45) × 10 −12 , 1,1‐dichloroacetone (4.16 ± 0.57) × 10 −13 , and 1,1,3‐trichloroacetone (<2.4 × 10 −12 ). © 2000 John Wiley & Sons, Inc.
