Determination of the 13C NMR chemical shifts in an a2u type iron(III) porphyrin cation radical.
The 13C NMR chemical shifts of all the carbons in an a2u type iron(III) porphyrin radical cation, [Fe(TPP)Cl]+, have been determined for the first time by the titration method as well as by the chemical shift correlation; they are 2230, 1050, and -1910 ppm for the alpha-pyrrole, beta-pyrrole, and meso carbon atoms, respectively.
