—The anaerobic photoreduction of hematoporphyrin by organic reducing agents in fluid aqueous solutions has been studied by electron spin resonance spectroscopy. Efficient photoreduction occurs with many hydrogen-atom or electron donors, including c

Using spin stabilization, ESR measurements have been made of o-semiquinone production from the horseradish peroxidase-H2O2 oxidation of catecholamine substrates. The termination rate constant for semiquinones stabilized with Zn2+ at pH 5 is about 10(
