Abstract
Effects of solute concentration and pH on the yields of products from X-irradiated aqueous solutions containing i-PrOH+N2O, Fe(CN)4– 6+Fe(CN)3– 6+N2O or NO– 2+N2O have been measured. Radical yields increase with increase of solute concentration and at pH>11. These results are interpreted in terms of conversion of H to e– aq at high pH and reaction of a species other than e– aq possibly an excited water molecule, with N2O.
