At 403 K, secondary production of Cl( 2P J) was observed under all experimental conditions. The title reaction is too show to be important in atmospheric chemistry.关键词: Experimental/ atom-molecule reactions chlorine molecular fluorescence organic compounds reaction kinetics theory reaction rate ...
reaction rate constantsstructure–activity relationshipssupport vector machineThe rate constants (k OH ) of the reactions between organic micropollutants with hydroxyl radical (OH) in aqueous systems are an important parameter to evaluate the persistence of organic compounds in the environment. In this ...
Hydrogen atoms produced by the electron-proton neutralization reaction in aqueous solution show abnormal esr lines because of an initial nonequilibrium population of the four possible electron-nuclear spin levels. The high-field line is observed in enhanced absorption and the low-field line in emission...
The reaction of methyl iodide with di(4-thiocresol)(2,2′-bipyridyl) platinum(II) to give iodo (methyl) di(4-thiocresol)(2,2′-bipyridyl) platinum(IV) follows the rate law, rate=K2[Pt-(4-thiocresol)2 (2,2′-bipyridyl)] [MeI]. The values of K2 increase with increasing polarity ...
A subset of the latter group includes electron transfer reactions for which the rate constants of both the forward and the reverse reaction have been measured. The radicals were generated by radiolysis, photolysis, thermolysis, or chemical reactions, and their rate constants were determined generally ...

The rates of cleavage have been measured of some R 3SiC 6H 4OMe- p compounds in aqueous methanolic perchloric acid at 50°. The relative reactivities of the compounds in which R = p-MeC 6H 4, and p-ClC 6H 5 indicates that electron release from R facilitates reaction. The low reactivity...
Relative rate constants for the reaction of OH radicals with a series of α,β-unsaturated carbonyls have been determined at 299 ± 2 K, using methyl nitrite photolysis in air as a source of OH radicals. Using a rate constant for the rea... R Atkinson,SM Aschmann,JN Pitts - 《Internatio...
