Hemoglobin structure and function

The observation of a new resonance in the 13C n.m.r. spectrum of a high spin iron(III)meso-tetraphenylporphyrin, the resolution of previously unresolved spin–spin splittings, and the synthesis of a 13C enriched porphyrin permit a complete reassignment of the spectrum which shows unexpectedly large paramagnetic shifts of the ortho phenyl carbon resonances previously assigned to pyrrolic carbon signals.
