摘要：
The influence of the properties of the axial ligands in heme proteins on the electronic structure of the iron(III) ion has been studied through angular overlap calculations. In particular, a correlation between (a) ligand field parameters and spectroscopic data and (b) the reduction potentials of the iron ion is proposed. The results of this approach are discussed with respect to their relevance for the biological function of different heme proteins.
