; ;
The formation of radicals in irradiated methyl and ethyl acetates and formates and their deuterated analogs was studied using nitroso compounds and nitrone. After irradiation at 77K only adducts with the radicals CH/sub 2/COOR, COOR, and MeCOOCHR are observed, but on irradiation in the liquid phase the radicals CH/sub 3/ C/sub 2/H/sub 5/, RCOOCH/sub 2/ CH/sub 2/, CH/sub 3/O and C/sub 2/H/sub 5/O also are detected. The radicals are formed in ion-molecule reactions and also as a result of rearrangement and fragmentation of the primary cation radicals and the decomposition of anion radicals and excited states.
