Photoreduction of IrCl62? complex in alcohol solutions and its reaction with hydroxyalkyl radicals
摘要:
The photochemistry of IrCl62- complex in simple alcohols have been studied using laser-flash photolysis. Single electron transfer from the solvent molecule to the light-excited complex has been shown to be the primary photochemical process. Quantum yields of the photoreduction of IrCl62- complex and the rate constants of its reaction with hydroxyalkyl radicals were determined at 200-330 KI Deviations of the rate constants from Debye-Smoluchowski equation for diffusion-controlled reactions are discussed.

updated rateconstants for 1-butanol and TBHP kinetics that influence the near-first-order OH concentration decay under the present experimental conditions, and this mechanism was used to facilitate the rateconstant determination. The current work improves upon previous experimental studies of the title rateconstant by utilizing a rigorously generated kinetic model to describe secondary reactions. Additionally
