Estimations of OH radical rate constants from H-atom abstraction from C?H and O?H bonds over the temperature range 250-1000 K

Rate constants for overall H-atom abstraction by hydroxyl radicals from C? H and O? H bonds are estimated for alkanes, haloalkanes, aldehydes, ketones, ethers, alcohols, nitriles, and nitrates over thetemperature range 250–1000 K. These estimated rate constants utilize the modified Arrhenius expression K = A'T²e^?E'/T in combination with the recommendations given in the recent review and evaluation of OH radical kinetics of Atkinson [1]. This estimation procedure gives good agreement, generally to within better than a factor of 2, of the estimated rate constants with theserecommendations.
