Atmospheric chemistry of cyclohexane: UV spectra of c-C6H11* and (c-C6H11)O2* radicals, kinetics of the reactions of (c-C6H11)O2* radicals with NO and NO2 and the fate of the alkoxy radical (c-C6H11)O*
Article Abstract:
The ultraviolet spectra of c-C6H11* and (c-C6H11)O2* radicals and the kinetics of the reactions of (c-C6H11)O2* radicals with NO and NO2 were investigated using the pulse radiolysis technique. The reaction of (c-C6H11)O2* radicals with NO was found to yield a (16 +/= 4)% of the nitrate (c-C6H11)ONO2 with a balance of reaction yielding (c-C6H11)O radicals and NO2. Results also suggested that no chemical activation is involved in the fate of (c-C6H11)O* radicals.

Measurement of the OH reaction rate constants for CF3CH2OH, CF3CF2CH2OH, and CF3CH(OH)CF3
Article Abstract:
The laser-induced fluorescence technique was combined with discharge flow, laser photolysis or flash photolysis methods to measure the OH reaction rate constants for CF3CH2OH, CF3CF2CH2OH and CF3CH(OH)CF3 at the temperature range 250-430K. The effects of impurities on the measured rate constants were also examined through sample purification using gas chromatography. Results showed no sizable effect of impurities for all three fluorinated alcohols.

Rate constants for the reactions of hydroxyl radical with several alkanes, cycloalkanes, and dimethyl ether
Article Abstract:
The rate constants for the reactions of OH with propane, n-butane, n-hexane, cyclopropane, cyclobutane, cyclohexane, cyclopentane and dimethyl ether were investigated. A persistent discrepancy was observed between absolute and relative rate measurements in the low temperature regime. Results also suggested that relative rate constant values can be used in simple Arrhenius expressions.
