title: Spectral characterization of vanadium-transferrin systems.
abstract: The preparation procedure of vanadium(III) transferrin and its stability are confirmed to be as previously reported. The electronic spectra of vanadium(III), oxovanadium(IV), and vanadium(V) transferrin derivatives are comparatively discussed. A band in the near infrared of the oxovanadium(IV) derivative is observed for the first time.
