modulation spectrometer (m.m.s.) has been modified to extend its operating temperature into a regime where methyl reactions of current interest may be conveniently studied. In this paper we present the first direct measurements on the reaction of methyl radicals with isobutane in the range478 ⩽T/K ⩽ 560.

The first direct measurements on the reaction of methylradicals with formaldehyde have been made using a molecular modulation spectrometer. These measurements have been complemented by product studies and a simple kinetic analysis to extract the rate constant which is satisfied by k5=(1.4 ± 0.1)× 10–12 exp (–29.1 ± 0.4 kJ mol–1/RT) in the range500 ⩽T/K ⩽ 603.
Kinetic Studies of the Reactions CH<sub>3</sub> + NO<sub>2</sub> → Products, CH<sub>3</sub>O + NO<sub>2</sub> → Products, and OH + CH<sub>3</sub>C(O)CH<sub>3</sub> → CH<sub>3</sub>C(O)OH + CH<sub>3</sub>, over a Range of Temperature and Pressure

The title reactions were investigated using pulsed laser photolysis combined with pulsed laser induced fluorescence detection of CH3O to determine the rate coefficients for CH3 + NO2 → products (3) and CH3O + NO2 → products (5) as a function of temperature and pressure, and to estimate the yield of CH3 (and thus the yield of CH3C(O)OH) from the reaction of OH with CH3C(O)CH3 (2) at two different temperatures

The complementary techniques of pulse-radiolysis and e.s.r. spectroscopy have been employed in a kinetic study of the dehydration of a variety of α,β-dihydroxyalkyl radicals [˙CR1(OH)CR2R3OH] into the appropriate carbonyl-conjugated radicals [˙CR2R3C(O)R1]. The overall rates of proton-catalysed dehydration, as revealed by steady-state (e.s.r.) and time-resolved (pulse-radiolysis) experiments, indicate
