2H-Mims ENDOR spectra of the diiron(III,IV)–W species generated in deuterated buffers. Signals arising from protonated species are observed over the swept magnetic fields. The signal shows minor changes upon saturation at g = 1.9875 to 2.0 and does not correlate with the tryptophan radical. The corresponding proton scale is shown for comparison.
