Valence formulas are constructed for the iron–ligand groups of the oxy‐, carboxy‐, nitric oxide‐, and nitrosobenzene derivatives of haemoglobin. To do this, the newly developed “increased‐valence” theory 3 is used. The most stable of these valence formulae are able to account simply for certain iron‐ligand properties, with the iron remaining essentially as ferrous, as it is in haemoglobin.
