The charge transfer reaction of cysteine hydrochloride with tetrachlorobenquinone in borax buffer solution gives a 1∶1 complex with an apparent molar absorptivity of 8.7×103 L· mol -1 · cm -1 at 354nm. The linear range is of 2—18μg/mL.
The structures and energies of reactant, product, intermediate, transition-state, and second-order saddle-point in the transfer reaction of inner hydrogen atoms in porphine are calculated by using B3LYP/6-31G ** method under certain symmetry restriction.
A theoretical study of the mechanism and kinetics of the inner hydrogen atom-transfer process in oxa-porphyrin (OPH) and thia-porphyrin (SPH) was presented. The structures and energies of reactants, products and transition-states in the transfer reaction of inner hydrogen atoms in OPH and SPH were calcu- lated with B3LYP/6-31G** method under certain symmetry restriction.
The ratio of hydrolysis and transfer reaction rates for cellobiose conversion was calculated.
It is suggested that the main effect of small additives on the photochemical chain reaction is due to a change in the reactivity of ionradical pairs, the primary products of a photoinduced electron transfer reaction at the initiation step.
Regression Analysis of Rate Parameters for the Photoinduced Electron Transfer Reaction
Experimentally, it was proved that there is no spin forbiddance in the photoinduced electron transfer reaction between these reactants.
