A variety of relative and absolute techniques have been used to measure the reactivity of fluorine atoms with a series of halogenated organic compounds and CO. The following rate constants were derived, in units of cm3 molecule-' s-l: CH3F, (3.7 2 0.8) X CH3C1, (3.3 2 0.71 X 10 -'I; CH3Br, (3.0 2 0.
Pulse radiolysis was used to study the kinetics of the reactions of CH 3 C(O)CH 2 O 2 radicals with NO and NO 2 at By monitoring the rate of formation and decay of NO 2 295 K. using its absorption at the rate constants 400 and 450 nm k(CH C(O)CH O ϩ NO) ϭ (8 Ϯ 3 2 2 and were de-Ϫ12 Ϫ12 3 Ϫ1 Ϫ1 2) ϫ
## Abstract Pulse radiolysis techniques were used to measure the gas phase UV absorption spectra of the title peroxy radicals over the range 215–340 nm. By scaling to σ(CH~3~O~2~)~240 nm~ = (4.24 ± 0.27) × 10^−18^, the following absorption cross sections were determined: σ(HO~2~)~240 nm~ = 1.29 ± 0
Based on a n FTIR-product study of the photolysis of mixtures containing Br,-CH3CH0 and Br,-CH3CHO-HCHO in 700 torr of N,, the rate constant for the reaction Br + CHBCHO + HBr + CH3C0 was determined to be 3.7 x lo-', cm3 molecule-' sf'. In addition, the selective photochemical generation of Br at A
