Mössbauer Spectra of Iron Tetraphenylporphins

Abstract

Abstract Mössbauer spectra were measured for a series of the central iron in Fe(II)- and Fe(III) complexes of tetraphenylporphin. The electronic structure of the central iron in the complex was modified by the axial ligand field. The Mössbauer spectra assigned the most probable electronic configurations to various iron states in the iron porphins.
