In the y-radiolysis of N2O/O2 saturated aqueous solution of 1,4-cyclohexadiene (CHD) (10 mM), the major final products are benzene with a radiolytic yield of 2.8 x 10 molJ (higher than the yield for electron beam pulse radiolysis, where it is 1.6 x 10 ) and 6-hydroxycyclohex-3-enyl hydroperoxide with the same radiolytic yield (1.5 x 10 and 1.3 X 10 mol J ) for the trans and cis isomers. The other major products are hydrogen peroxide (yield = 2.3 x 10 mol J ), formaldehyde (0.7 x 10 ), acetaldehyde (0.44 x... 

Role of Radiolytic Hydrogen Peroxide. A series of experiments were carried out to determine the extent to which radiolytic H202 contributed to the decrease in oxygen capacity of irradiated hemocyanin. From these experiments summarized below, the conclusion is drawn that the effects of gamma irradiation of hemocyanin in solutions of hemolymph or buffer in the dose range of 0 to 60 krads are caused nearly entirely by H202. The experimental bases for this conclusion follow ... 

Hydroxyl radical. The —O—O— bond in hydrogen peroxide, at ca. 213 kJ/mole [7], is relatively weak, and is susceptible to homolysis by a variety of methods including thermal, photolytic/radiolytic and metal redox. The active species produced is the hydroxyl radical generation by UV irradiation at 254 nm giving two per mole of H2O2 ...
