Measurement of the rate constants of the reactions of the chlorine atom with C3F7I and CF3I using the resonance fluorescence of chlorine atoms

Abstract

The rate constants of the reactions of the chlorine atom with C 3 F 7 I (k 1 ) and CF 3 I (k 2 ) have been measured using the resonance fluorescence of chlorine atoms in a flow reactor at 295 K: k 1 = (5.2 ± 0.3) × 10 -12 cm 3 molecule -1 s -1 and k 2 = (7.4 ± 0.6) × 10 -13 cm 3 molecule -1 s -1 . No iodine atoms have been detected in the reaction products.
