Abstract
1 1 3Cd NMR has been used to examine the Cd–CdO solid solution. A series of samples prepared under different conditions was analyzed for percent Cd(0) using a direct chemical analysis. Conduction electrons arising from the ionization of Cd(0) appear to be affected by the chemisorption of water on the CdO surface. The conduction electrons influence the resonance frequencies and spin-lattice relaxation times of the Cd(II) moieties detected in Bloch decay experiments. The low-shielding signals observed for CdO samples have a variable linewidth, which correlates directly to the temperature of sample preparation. Selective saturation, Hahn spin echo and two-dimensional NMR experiments showed that this line width is produced by an inhomogeneous broadening mechanism, probably resulting from a distribution of CdO crystallites having different Cd(0) concentrations. Korringa-relation predictions of spin-lattice relaxation as a function of resonance frequency confirm the importance of conduction electron concentrations in determining the 113Cd NMR parameters.
