Abstract

Electron paramagnetic resonance spectra of azidosemimethemerythrin (from Phascolopsis gouldii) have been integrated to find the total number of spins per monomer unit. The value observed, 1.0 ± 0.1 spins per Fe2 pair, confirms the assignment of a hybrid oxidation state, FeIIFeIII, to each site.
