Paper Abstract
Absolute rate constants for the reactions of OH radicals with CCl3CHO and CF3CHO have been determined as a function of temperature using a pulsed laser photolysis-resonance fluorescence technique. The rate constant for reaction with CCl3CHO, k(CCl3CHO) equals 1.4 +/- 0.2 cm3 molecule-1 s-1, was found to be virtually independent of temperature over the range 233 - 313 K while the Arrhenius expression obtained for reaction with CF3CHO was k(CF3CHO) equals 3.5 +/- 1.0 X 10-12 exp [-(488 +/- 57)/T] cm3 molecule-1 s-1. Reactivity trends and atmospheric implications are discussed.
