Pulse Radiolysis of Crystalline Ice and Frozen Crystalline Aqueous Solutions

Pulse radiolysis of aqueous thiocyanate solution.

The pulse radiolysis of N(2)O saturated aqueous solutions of KSCN was studied under neutral pH conditions. The observed optical absorption spectrum of the SCN(*) radical in solution is more complex than previously reported, but it is in good agreement with that measured in the gas phase. Kinetic traces at 330 and 472 nm corresponding to SCN(*) and (SCN)(2)(*-), respectively, were fit using a Mo...

Acetonylperoxyl Radicals, CH3C0CH20 2: A Study on the y-Radiolysis and Pulse Radiolysis of Acetone in Oxygenated Aqueous Solutions

Hydroxyl radicals from the radiolysis of N20 / 0 2 (4:l)-saturated aqueous solutions of acetone (10 3 mol dm -3) react with the solute by H-abstraction thereby forming acetonyl radicals. As shown by pulse radiolysis, the acetonyl radicals rapidly add oxygen (k = 3 x 109 dm3m ol_1s_1) thereby forming acetonylperoxyl radicals which decay by second-order kinetics (2 k = 8 x 10* dm3mol 's -1). Unde...

Hydroxyl Radical-Induced Oxidation of Ethanol in Oxygenated Aqueous Solutions. A Pulse Radiolysis and Product Study

y-Radiolysis of N20-saturated water or photolysis of aqueous H2O2 provided a source of OH radicals. These radicals react with ethanol by preferentially abstracting an H atom at C-l. In the presence of oxygen these radicals are converted into the corresponding peroxyl radicals. The a-hydroxyethylperoxyl radicals decay by first order kinetics (k = ki + k2 [OH -]) acetaldehyde and H02/H+ + 01 bein...
