Magnetic resonance of cobalt(II) and iron(III): A Schiff's base and heme proteins

This thesis is comprised of three parts. In the first, the Co-59 nuclear quadrupole coupling constants for cobalt-doped nickelbis(benzoylacetone)ethylenediimine were determined by EPR spectroscopy. The three rotation axes for the three single crystals were not exactly perpendicular to each other, but their exact orientations were known by X-ray diffraction analysis. The program IMOFT, developed for this study, was used to determine the elements of the g matrix, and, consequently, the principal g values and their orientations were found. The principal values of the hyperfine coupling constant A and quadrupole coupling constant P and their orientations were obtained by using the simulation program DXTAL to fit the experimental spectra of the single crystals. The quadrupole coupling constants are QD = $-$4.8 MHz and QE = 0.30 MHz, and they are interpreted by the ground electron configuration--$\rm (dx\sp2-y\sp2)\sp2(dz\sp2)(dxz)\sp2(dyz)\sp1.$
