A flow system has been developed to study relative rate coefficients of hydroxyl radicals reacting with alkanes under conditions relating to tropospheric chemistry. Relative Arrhenius parameters have been measured over the temperature range 243-328 K for pairs of alkanes from a list consisting of n-

The rate constant for the gas-phase reaction of the hydroxyl radical with trifluoroacetic acid has been determined over the temperature range 283-323 K using a relative rate technique. The results provide a value of k( OH+CF,C(O)OH) = 2.O~lO-\*~exp(-l46~500/T)cm~molecule~'s-'basedonk(OH+C~H,)=7.8~lO
Rate coefficients for OH reactions with the 2-5 carbon aliphatic aldehydes have been measured under pseudo first-order conditions in OH. OH was generated by flash photolysis of H 2 0 a t wavelengths greater than 165 nm and its concentration monitored using time-resolved resonance fluorescence spectr
The relative hydroxyl radical reaction rate constants from the simulated atmospheric oxidation of selected acetates and other esters have been measured. Reactions were carried out at 297 2 2 K in 100-liter FEP Teflon@-film bags. The OH radicals were generated from the photolysis of methyl nitrite in
