Isir 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...
متن کاملAcetonylperoxyl 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...
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...
