Fourier transform infrared spectroscopy was used to measure relative rate constants at 298 plus or minus 3 K for the reactions of hydroxyl radicals with cyclohexene, cyclopentene, and glutaraldehyde by photolyzing HONO in air containing ppm levels of one of these species and trans-2-butene or propene as reference compounds. The rate constants (X10 super(11) cm super(3) molecule super(-1) s super(-1)) measured were as follows: 540 plus or minus 1.10 for cyclohexene, 4.99 plus or minus 1.07 for cyclopentene, and 2.23 plus or minus 0.46 for glutaraldehyde, using an absolute rate constant of (6.37 plus or minus 1.27) X 10 super(-11) cm super(3) molecule super(-1) s super(-1) for the reaction of OH with trans-2-butene; and 6.1 plus or minus 1.0 for cyclohexene, 5.7 plus or minus 1.0 for cyclopentene, and 2.53 plus or minus 0.39 for glutaraldehyde, using an absolute rate constant of (2.63 plus or minus 0.39) X 10 super(-11) cm super(3) molecule super(-1) s super(-1) for propene.
