Rate constants for the reactions of OH with CH3Cl, However, for the chloromethanes all the rate constants are lower at atmospheric temperatures than previously reported, especially for CH 2 Cl 2 where the present rate constant is about a factor of 1.6 below the JPL 92‐20 value. The new rate constant appears to resolve a discrepancy 2 as the OH source. The 298 K rate constant for OH + C 3H 8 was found to be (1.15 ± 0.1) × 10 −12 cm3 s 1, in excellent agreement with the litera-ture recommendation, and with a separate determination us-ing HNO 3 photolysis at 248 nm as the OH source. The 298 K rate constants for OH + n−C 3H 7I and i−C 3H 7I were mea- The OH + SO2 reaction plays a critical role in understanding the oxidation of SO2 in the atmosphere, and its rate constant is critical for clarifying the fate of SO2 in the atmosphere. The rate constant of the OH + SO2 reaction is calculated here by using beyond-CCSDT correlation energy calculations for a be Rate constants for the gas-phase reactions of the OH radical with a series of aromatic hydrocarbons at 296 ± 2 K. the xylenes, and the trimethylbenzenes. Using the recommended literature rate constant for the reaction of OH radicals with propene of (2.66 ± 0.40 The atmospheric oxidation mechanism of 1,2,4-trimethylbenzene If the rate constants (k tot) for a number of simple alkanes are known, the experimental data can be fit to obtain best values for k p, k s, and k 1. These can then be used to predict the rate constant for the reaction of OH with an alkane where experimental measurements have not been made. Relative rate experiments were used to measure ratios of rate constants as a function of temperature for the reactions of OH with propane, n-butane, n-pentane, n-hexane, cyclopropane, cyclobutane, cyclopentane, cyclohexane, and dimethyl ether. To assure internal consistency, ratios were measured for seventeen reactant pairs among these reactants.
