Abstract
AbstractThe paper evaluates the possibilities and limitations in characterising photochemical properties of individual kinetically labile species being in mutual equilibrium. A model of calculating quantum yield values is elaborated and applied to azidokojic iron(III) complexes in aqueous solutions. Based on the known speciation of the complexes as a function of pH, Fe(III) and azidokojic acid concentrations, electronic absorption spectra of individual species, and the determined overall quantum yield of Fe(II) photoformation at irradiation with monochromatised radiation at 366 nm, the quantum yield of Fe(III) to Fe(II) photoreduction was obtained for each of the complexes present in the investigated systems.
