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

摘要

n 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;MCD spectra were also obtained for (MoOBr;Part 2 of this thesis, metal surfaces have been characterized through the use of atomic force microscopy (AFM). The AFM was used to examine the interaction of anions with the Ag(111) electrode. It was found that perchlorate and chloride anions are not inert to the Ag(111) surface while sulfate ions do not perturb the system noticeably. In situ AFM images of underpotential deposition of Cd adlayers on Ag(111) were also collected. After the first deposition peak, the Cd forms a
