Fragmentation dynamics of the ethyl bromide and ethyl iodide cations: a velocity-map imaging study.
The photodissociation dynamics of ethyl bromide and ethyl iodide cations (C2H5Br(+) and C2H5I(+)) have been studied. Ethyl halide cations were formed through vacuum ultraviolet (VUV) photoionization of the respective neutral parent molecules at 118.2 nm, and were photolysed at a number of ultraviolet (UV) photolysis wavelengths, including 355 nm and wavelengths in the range from 236 to 266 nm. ...
متن کاملThermal effect of photolysis in 203Hg, 35S and 131I labeled mercury (II) iodide thiocyanate powders.
203Hg, 35S or 131I labeled mercury (II) iodide thiocyanate (HgISCN) powders were prepared, respectively. When the powders were exposed to sunlight, some parts of the crystals of the powders were decomposed and the decomposed atoms diffused toward crystal surface. This diffusion velocity was accelerated by thermal treatment of the darkened powders. The velocity is larger in order of 35S, 203Hg, ...
متن کاملDynamics of the A-band ultraviolet photodissociation of methyl iodide and ethyl iodide via velocity-map imaging with 'universal' detection.
We report data from a comprehensive investigation into the photodissociation dynamics of methyl iodide and ethyl iodide at several wavelengths in the range 236-266 nm, within their respective A-bands. The use of non-resonant single-photon ionization at 118.2 nm allows detection and velocity-map imaging of all fragments, regardless of their vibrotational or electronic state. The resulting photof...
متن کاملReductive degradation of perfluoroalkyl compounds with aquated electrons generated from iodide photolysis at 254 nm.
The perfluoroalkyl compounds (PFCs), perfluoroalkyl sulfonates (PFXS) and perfluoroalkyl carboxylates (PFXA) are environmentally persistent and recalcitrant towards most conventional water treatment technologies. Here, we complete an in depth examination of the UV-254 nm production of aquated electrons during iodide photolysis for the reductive defluorination of six aquated perfluoroalkyl compo...
