β¦ Synopsis
The design and performance of a smog chamber for the study of photochemical reactions under simulated environmental conditions is described. The chamber is thermostated for aerosol experiments, and it comprises a gas chromatographic sample enrichment system suitable for monitoring hydrocarbons at the ppbv level. By irradiating NO x/alkane-mixtures rate constants for the reaction of OH radicals with n-alkanes are determined from n-pentane to n-hexadecane to be

The rate coefficients for the reactions of OH with ethane ( k l ) , propane (kz), n-butane (k3), iso-butane (k4), and n-pentane ( k 5 ) have been measured over the temperature range 212-380 Kusing the pulsed photolysislaser induced fluorescence (PP-LIF) technique. The 298 Kvalues are (2.43 2 0.20) X
Recently, Atkinson et al. have developed a more sophisticated approach than simple additivity to determine group rate constants a t room temperature for reactions of OH radicals with alkanes. In this article, use is made of reliable experimental data a t room temperature and at 753 K to determine te

An error was discovered in the method used for calculating the moments of inertia for the internal rotations in the activated complex. In order to retain good agreement between theory and experiment, it was necessary to change some other molecular parameters of the activated complex. The following c
## Abstract Using methyl nitrite photolysis in air as a source of hydroxyl radicals, relative rate constants for the reaction of OH radicals with a series of alkanes and alkenes have been determined at 299 Β± 2 K. The rate constant ratios obtained are: relative to __n__βhexane = 1.00, neopentane 0.1
