Fig. 9. Proton NMR spectra at 220 Me of solutions in d5-pyridine of the Zn(II)-complexes with porphin, and the dimethylesters of mesoporphyrin IX, deuteropor-phyrin IX, and protoporphyrin IX. The resonance assignments were based on the relative resonance intensities and the observed fine-structure from spin-spin coupling they agree with previously published data by Caughey and Koski (17 a = ring methyls (for porphin protons at positions 1 to 8), b = mesoprotons, c and d = methylene protons of the propionates, e = methylesters, / and g = resonances of the substituents at positions 2 and 4. Three strong resonances between —7 and —9 ppm come from d5-pyridine, the line at ca. —4.9 ppm from HDO. T = 25 °C... Fig. 9.
