Reconsidering early and recently published magnetic susceptibility data, we find that the assumption about the full diamagnetism of oxy‐ and carbonmonoxy‐derivatives of hemoglobins is not warranted. It appears that these derivatives display a variety of magnetic states of the iron ligand complex, depending on conditions which must still be elucidated in full. The bearing of these results on debates of the past, the recent evidence from other spectroscopic techniques and the perspectives for future work are briefly discussed.
