Paramagnetic 19F n.m.r. spectra of iron(III) porphyrins substituted with CF3 groups and reconstituted myoglobin

Paramagnetic 19F n.m.r. spectra of iron(III) porphyrins substituted with CF3 groups and metmyoglobin reconstituted with the iron(III) complex of 3-trifluoromethylmesoporphyrin-IX were measured and the 19F shifts compared with the respective chemical shifts of the free ligands and zinc(II) complexes.
