The rate constant for the reaction of the OH radical with 2-butanol was measured using a relative rate method; the rate constant was determined to be (9.2 +/- 2.4) x 10(-12) cm(3) molecule(-1) s(-1) at 296 +/- 2 K, where the indicated error includes the estimated overall uncertainties in the rate constant for the reference organic (cyclohexane). The formation yield of 2-butanone from the reaction of the OH radical with 2-butanol was determined to be 0.695 +/- 0.073. Using this 2-butanone formation yield from the OH radical reaction with 2-butanol, the OH radical formation yields from the reactions of O-3 with 2,3-dimethyl-2-butene, 2-methyl-2-butene, alpha-pinene, and sabinene were determined to be 0.80 +/- 0.12, 0.93 +/- 0.14, 0.76 +/- 0.11, and 0.33 +/- 0.06, respectively. These OH radical formation yields agree to within +/-25% with the yields previously derived using cyclohexane to scavenge OH radicals and measuring the amounts of cyclohexanone plus cyclohexanol formed. Our present OH radical formation yield for 2,3-dimethyl-2-butene is also in good agreement with the value of 0.7 previously reported from a comprehensive product study.
