Paramagnetic hyperfine interactions, induced by strong applied magnetic fields, result in Mössbauer spectra that contain a wealth of information about the symmetry of the active site iron atomo Quantitative evaluation of the data relies on a spin Hamiltonian formalism that appears to work quite we110 Model calculations utilizing low-symmetry (tric1inic) crystal fields have also been developed and applied to the data. In addition, comparative studies yield information pertaining to the axial ligands of cytochrome P-450, ch1oroperoxidase, horseradish peroxidase and hemoglobin. A technique that allows the determination of zero-field splitting parameters in high-spin ferrous compounds is also described. This method does not depend on sample concentration, and ""non-iron"" spin impurities do not affect the resu1tso Application to ferrous f1uosilicate yields a value of D 15 K that is compatible with magnetic susceptibility investigations."
