Scandium Coordination in Solid Oxides and Stabilized Zirconia:

Jul 07, 2006· 45Sc NMR isotropic chemical shifts and quadrupole coupling constants of several scandium-containing solid oxides have been measured. Both parameters prove to be sensitive to local structure. In particular, in these materials the 45Sc isotropic chemical shift appears to be dominated by the first neighbor coordination environment, i.e., the coordination number.
