چکیده
The photoionization of isopropanol (i-PrO H) at 11.7 e V has been investigated in the NBS high pressure photoionization mass spectrometer over the pressure range 0.1 to approximately 200 millitorr_ The major primary ion, CHaCHOH+, reacts with a total rate coefficient of 1.1 ± 0_1 X 109 cma/molecule-s to yie ld mainly (i-PrOH)H+ and CH3(i-Ca H,)COH+ _ At pressures in excess of a few millitorr consecutive reactions of (i-PrOH)H+ and CHa(i-CaH,)COH+ were also detected, including the overa ll dehydration process

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 کاملWater radiolysis by gamma –irradiation for high quality synthesis of Nickel Oxide nano sheet
A simple, time effective and cost effective, methos was reported for synthesis of nickel oxide nanostructure. The NiO nanostructure was synthesized by gamma-irradiation method from NiSO4 precursor. The solution was irradiated by 60Co gamma-ray source at the dose rate of 40 Gy/min for determined time. The synthesized powders are characterized by means of X-ray powder diffraction (XRD), Energy-di...
متن کاملExperimental Study of Radiolytic Oxidation of Pyrite: Implications for Mars- Relevant Crustal Processes
Introduction: Radiolytic dissociation of water produces a highly reactive combination of oxidizing (e.g., H 2 O 2 , OH radicals, and O 2) and reducing (e.g., H atoms and H 2) species [1]. In subsurface environments , radiolysis can produce gradients of both electron acceptors and electron donors that are possible sources of metabolic energy [2]. Radiation-induced chemical reactions have particu...

A detailed outline is given of how pressure can be used as a mechanistic indicator in kinetic studies of chemical reactions in solution that are induced by flash photolysis and pulse radiolysis. These techniques have mainly been applied to tlie study of organometallic and bioinorganic reactions including processes such as ligand substitution, binding of small molecules, formation and breakage o...
