Characterization of metal sites. I. In molybdoenzymes and their model systems, and, II. On silver electrode surfaces

In part 1 of this thesis, the characterization of molybdenum complexes and some molybdoenzymes was made through the use of optical and magnetic circular dichroism (MCD) spectroscopy. MCD spectra were obtained for (MOCl$\sb4$) $\sp-$ (M = Cr, and Mo) and (WOCl$\sb4$(H$\sb2$O)) $\sp-$ compounds. All of the spectra display temperature and field dependence consistent with a paramagnetic ground state. The two lowest energy bands are assigned to the $d\sb{xy} \to d\sb{xz},d\sb{yz}$ and $d\sb{xy} \to d\sb{x\sp2-y\sp2}$ ligand field transitions. All of the compounds display vibronic structure on the $d\sb{xy} \to d\sb{xz},d\sb{yz}$ band arising from coupling with the totally symmetric M-O stretch. The third band is assigned to a b$\sb1$(Cl) to b$\sb2(d\sb{xy})$ charge transfer transition and at slightly higher energies are charge transfer transitions from orbitals with e symmetry to the half occupied $d\sb{xy}$ orbital.
