Reactions of flavosemiquinone radicals in the presence of metal ions

The rate constants of disproportionation of flavosemiquinone radicals were obtained by pulsed spectroscopy. The yield of the flavosemiquinone radical increased when Mohr’s salt was introduced in the aqueous solutions of riboflavin. The spectral kinetic characteristics of complexes of flavosemiquinon...

Zusammenfassung:	The rate constants of disproportionation of flavosemiquinone radicals were obtained by pulsed spectroscopy. The yield of the flavosemiquinone radical increased when Mohr’s salt was introduced in the aqueous solutions of riboflavin. The spectral kinetic characteristics of complexes of flavosemiquinone radical anions with Zn 2+ and Cd 2+ ions were determined.
