Six free radicals were observed when an aqueous solution of H/sub 2/O/sub 2/ and ..cap alpha..-methyl-D-glucopyranoside was photolyzed using the in situ photolysis ESR method: a C6 primary hydroxyalkyl radical, a C2 secondary hydroxyalkyl radical, a C7 primary oxyalkyl radical, a C1 primary oxyalkyl radical, C3 secondary hydroxyalkyl radical, and a C5 secondary oxyalkyl radical. The pH dependence of the concentraion of these species, their reactions, stereochemical factors influencing radical stability, and comparison with product analysis studies are discussed.
