They propose a comprehensive study of the oxygen-17 nuclear                     magnetic resonance spectroscopic behavior of a range of oxide                   superconductors in their normal, and in many cases,                             superconducting, state.  Newer systems will naturally be                        included, as they become available, as will a series of model                   perovskites and copper oxides.  They will obtain knight shift,                  linewidth, and spin-lattice (Korringa and Arrhenius) relaxation                 time (T1) behavior of each of these systems, and relate there to                structure, and to the experimental Tc temperatures observed.                    Where appropriate, oriented samples will be used, to facilitate                 spectral assignments.  They will investgigate the kinetics of                   oxygen exchange; the effects of sequential oxygenation on                       NMR/superconducting behavior; the topic of "frozen" states; melt                textured growth and the removal of "weak links".
