We have developed a system to measure redox potentials for oxometalloporphyrin model compounds that takes advantage of your fast, reversible oxygen atom transfer in between oxometal complexes and halide ions.[6] By using rapidmixing stoppedflow spectroscopy, price constants of each forward and reverse reactions areSupport of this study by the National Institutes of Health (2R37 GM036298), the European Social Fund (080935557) along with the European Union integrated project, Peroxicats (265397) are gratefully acknowledged.
