## Abstract We propose a semiempirical procedure for the estimation of the rate constants for hydrogen atom abstraction reactions of OH radicals with haloalkanes and haloethers. Our procedure is derived from the collision theory based kinetic equation, which was originally proposed by Heicklen (__I

β¦ Synopsis
Rate constants for overall H-atom abstraction by hydroxyl radicals from C -H and 0 -H bonds are estimated for alkanes, haloalkanes, aldehydes, ketones, ethers, alcohols, nitriles, and nitrates over the temperature range 250-1000 K. These estimated rate constants utilize the modified Arrhenius expression k = A'T'e -E IT in combination with the recommendations given in the recent review and evaluation of OH radical kinetics of Atkinson 111. This estimation procedure gives good agreement, generally to within better than a factor of 2, of the estimated rate constants with these recommendations.
