Photochemistry of Fe(III) complex with glyoxalic acid in aqueous solution

Abstract

Nanosecond laser flash photolysis technique was used to study photochemistry of Fe(III) complex with glioxalic acid. The primary photochemical process was found to be inner-sphere electron transfer in the excited complex leading to formation of the long-lived radical complex [FeII … ·OOC-C(O)H]2+. A number of important spectral-kinetic parameters of this species were determined and mechanism of photolysis of Fe(III)-glioxalate complex was proposed. 1 The article was translated by the authors.
