✦ Synopsis

Abstract

^1^H NMR saturation transfer experiments were successfully used in connecting iron(III) high‐ and low‐spin forms of equine, the mollusc Dolabella auricularia and the shark Mustelus japonicus myoglobins. With the known signal assignments in the high‐spin form, a haem peripheral proton resonances in met‐azido and met‐imidazole complexes of the myoglobins have been straightforwardly assigned via the saturation transfer connectivities. Analysis of the extent of the saturation transfer provided the kinetics of the ligand exchange.
