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, O'cH3oclJ2 = (4.2 + 0.5)× 10 -18 cm 2 molecule-l
