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...
متن کاملGamma-radiolysis of aqueous solution of proline.
Gamma-radiolysis of 0.05 M neutral proline solution was investigated. As the main reaction of proline radiolysis in oxygenated solutions, the hydroxylation reactions leading to hydroxyproline formation and the reactions leading to the total destruction of the pyrrolidine ring were shown. In oxygen-free solutions the yield of these reactions decreased; in this medium combination reactions giving...
متن کاملGamma-radiolysis of aqueous solution of histidine.
The dependence of Gi(-M) values of histidine on the concentration of irradiated 10(-4) - 10(-1)M solutions, pH and the presence of O2, N2O and sec-butyl alcohol was investigated. In oxygen-free medium the maximum radiation sensitivity of histidine was found at pH 5--8; in oxygenated solutions it was shifted to the 6--1 pH range. The formation of radiation products was also studied. The course o...
متن کاملFormation of super-reduced Chromatium high-potential iron--sulphur protein in aqueous solution by pulse radiolysis.
Both the oxidized and reduced forms of Hipip (high-potential iron--sulphur protein) are reduced (approx. 30% yields) by eaq.- in a single-stage process, rate constants 1.7 x 10(10) and 1.8 x 10(10) M-1 . s-1 respectively, at 25 degrees C, pH 7.0 (5 mM-phosphate). Super-reduced Hipip, which is formed in the latter case, has a spectrum which closely resembles that of reduced ferredoxin, i.e. Fe4S...
متن کاملReaction of the hydrogen atom with nitrous oxide in aqueous solution – pulse radiolysis and theoretical study
UB3LYP/cc-pVTZ computations using C-PCM, IEF-PCM, and SMD water-solvent models have been performed for the reaction of the Hc atom with nitrous oxide (N2O) producing N2 and cOH in aqueous solution. The Hc atom attacks the oxygen atom in the N2O molecule resulting in the formation of the [H–ONN] transition state and its decomposition into cOH and N2. This direct path requires 54.2 kJ mol 1 (PCM)...
