The N-H stretching vibrations of the oxygenated 'hybrid' haemoprotein models with an axial hindered base indicate that there is no conventional hydrogen bond with the terminal oxygen of the Fe-O2 moiety, contrary to the models with an axial unhindered base; however, the Fe-O2 moiety is highly polarizable as indicated by O-17 NMR spectroscopy.
