Gamma-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 کاملRadiolysis of Liquid Propane: non-Radical Reactions
The yields of ionic and excited molecule reactions in y-radiolysis of liquid propane from 35 to -130C have been assessed by isotopic analysis of C3Hs-l-C3Ds+Oz and CH3CD2CH3 -1-02 mixtures. From a comparison with gas phase data the following conclusions are reached for the gas to liquid phase change: (a) the ionic decomposition yield rlecreases by :5 69 %, (b) the net excited molecule decomposi...
متن کاملPulse 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 کاملIsir Subpicosecond Pulse Radiolysis System
The highest time resolution of the pulse radiolysis had remained about 30 ps since the late 1960’s. To make clear the primary processes in the radiation chemistry and physics within 30 ps, we developed a stroboscopic pulse radiolysis system for the absorption spectroscopy with the time resolution of 2.0 ps (10-90% rise time). The time resolution of 2.0 ps was estimated from the time-dependent b...
