## Abstract The reaction of hydrogen atoms with diazomethane was used as a source of methyl radicals to study the reaction of oxygen atoms with methyl radicals. This investigation verifies directly the earlier results that formaldehyde is a major product and that the rate constant is greater than 3

β¦ Synopsis
The rate constants for the reactions between CD,Hf_, and 0 have been measured and found to be fast, independent of isotope. The branching ratio for these reactions has been found to be statistical. Since decay of metastable triplet CD*HO+ shows a large isotope effect, it was thought that the present reactions might also do so. The fact that the present experiments do not show this large isotope effect is ascribed to the large exothermicity of reaction CH: +O-tHCO++H,, which opens several alternative pathways not involving metastable triplet CD2HO+ as the intermediate.

## Abstract The reaction of methyl radicals with atomic and molecular oxygen was studied with a photoionization mass spectrometer. The methyl radicals were generated by reacting oxygen atoms with ethylene in a fastβflow tube reactor. The rate constant for the reaction of methyl radicals with oxygen
The reaction of 1,3-cyclopentadiene (CPD) with ground-state atomic oxygen O ( 3 P ) , produced by mercury photosensitized decomposition of nitrous oxide, was studied. The identified products were carbon monoxide and the following C4H6 isomers: 3-methylcyclopropene, 1,3-butadiene, 1,2-butadiene, and

The reactions of metastable decomposing methyl acetoacetate (a mixture of keto and enol tautomers) are reported and discussed. The unimolecular fragmentations of the tautomers are different. The metastable decomposing radical cation of the keto form displays four specific ions: [ M -CO] +', IM -CHzO
