Abstract
The rate constant for the reaction of CH2Cl2 with OH was measured by t he flash photolysis resonance fluorescence technique over the temperat ure range 277-370 K to give the following Arrhenius expression: k(DCM) = (2.61(-0.34)(+0.37)) x 10(-12) exp{-(944 +/- 29)/T} cm(3) molecule( -1) s(-1), where the uncertainties represent 95% confidence limits ass ociated with the statistical fitting procedure and include the contrib ution for the expanded uncertainties in the individual rate constant. Based on this new value, the results of recent relative studies of the OH reactions with CHCl2-CFCl2, CH2ClBr, CH2Br2, and CH2FCl have been reanalyzed.
