Abstract: The Mossbauer Spectra of the synthetic iron porphyrins Fe (OEP) Cl, Fe (NO2) (OEP)Cl, and Fe(NO2)2(OEP)Cl were measured at 77k, 300k and in anexternal megnetic field of 5KOe at room temperature. The Changes of the spectral shape was explained by electron Spin-Spin relaxation. The small difference of the isomer shift caused by the different number of NO2-groups substituted for the meso-positions in the pyrrole ring was discussed.
