Abstract

Electron nuclear double resonance (ENDOR) spectroscopy of oxoiron(IV) porphyrin π-cation radical complexes with pyrrole β-substituted porphyrins is reported. Hyperfine coupling constants (A ^H) of the pyrrole β-mefhyl groups were determined. Comparison of the A ^H values with those of compound I of peroxidase and catalase indicated the a _1u porphyrin π-cation radical states of these compound I.
