N2 - Alkyl and alkylperoxy radicals originating from dimethyl ether have been studied in the gas phase at 296 K. A pulse radiolysis-UV absorption technique was used. Absorption cross-sections were quantified over the wavelength range 220-350 nm. At 230 nm, σCH3OCH2 = (4.2 ± 0.5) × 10-18 cm2 molecule-1 has been obtained. Rate constants for the reaction of the alkylperoxy radical with NO and NO2 were determined to be (9.1 ± 1.0) × 10-12 cm3 molecule-1 s-1 and (7.9 ± 0.4) × 10-12 cm3 molecule-1 s-1, respectively.
