✦ Synopsis

Rate constants for the reactions of 1 -and 2-hydroxyethyl radicals with O2 and NO were measured at room temperature by laser flash photolysis-photoionization mass spectrometry method. The results are as follows (in units of cm3 moleculec' s-I): CH>CHOH+O> ((2.8+0.2)x10-I'); CH,CHOH+NO ((2.4kO.6)XlWI'); CH2CH20H+Og ((3.0f0.4)~10-I'); CH,CH,OH+NO ((2.6kO.7)~ lo-"). The reaction of l-hydroxyethyl radical with O2 was found to be approximately one order of magnitude faster than 2-hydroxyethyl radical. The reaction mechanism seems to be different for the two hydroxyethyl radicals.

Rate constants for the combination of methyl radicals with NO and 0 2 have been measured by flash photolysis of azomethane coupled with product analysis by gas chromatography. Values of the rate constants have been obtained over the pressure regiofi from 50 to 700 torr with He, NP, and Ar as quenchi

By allowing dimethyl peroxide ( 10-4M) to decompose in the presence of nitric oxide (4.5 X lOW5M), nitrogen dioxide (6.5 X 10-5M) and carbon tetrafluoride (500 Torr), it has been shown that the ratio kzlkz, = 2.03 f 0.47: CH30 + NO -CH30NO (reaction 2) and CH30 + NO2 -CH30N02 (reaction 2'). Deviatio
