Proton NMR Characterization of the Ferryl Group in the Model Heme Complexes and Hemoproteins: Evidence for the FeIV=O Group in Ferryl Myoglobin and Compound II of Horseradish Peroxidase

Article abstract of DOI:10.1021/ja00342a022

The proton NMR spectra of model porphyrin complexes possessing the ferryl, Fe^IV=O group are reported and assigned.The only resonance shifted well outside the diamagnetic region is that of the meso protons.Moreover, these model compounds exhibit
