Five inorganic rubidium salts, RbCl, RbClO{sub 4}, Rb{sub 2}SO{sub 4}, Rb{sub 2}CrO{sub 4}, and RbNO{sub 3}, were examined using {sup 87}Rb NMR spectroscopy. Significant line narrowing occurs under dynamic-angle spinning (DAS) compared to magic-angle spinning (MAS) or variable-angle spinning (VAS). From DAS spectra acquired at various magnetic field strengths, isotropic chemical shifts and isotropic second-order quadrupolar shifts were obtained. By simulations of single-site line shapes obtained from MAS-detected DAS experiments, complete chemical shift and quadrupolar parameters were determined for each of the three crystallographically distinct rubidium sites in RbNO{sub 3}. 28 refs., 6 figs., 4 tabs.
