Temperature dependencies of the Rb-87 quadrupole coupling constants (C-Q), asymmetry parameters (eta(Q)), and isotropic chemical shifts (delta(iso)) have been observed and determined for RbCl, RbClO4, Rb2SO4, and RbNO3 from variable-temperature (VT) Rb-87 magic-angle spinning (MAS) NMR spectra for the temperature range from about -100 to +165 degrees C. VT Rb-87 multiple-quantum MAS NMR spectra of the trigonal form for RbNO3 have assisted the retrival of C-Q, eta(Q), and delta(iso) for the three Rb sites of this phase. The results demonstrate that C-Q(Rb-87) and delta(iso)(Rb-87) are highly temperature-dependent for all samples over the studied temperature range. Linear correlations of delta(iso) with temperature, corresponding to temperature coefficients in the range -0.014 to -0.036 ppm/degrees C (i.e., increasing shielding with increasing temperature), are observed for all samples. An exception is the Rb(2) site in Rb2SO4 for which a small linear decrease in shielding is observed with increasing temperature. For RbClO4 and Rb2SO4 the three Ca(87Rb) values decrease linearly with negative temperature coefficients in the range -7.0 to -1.6 kHz/degrees C. Linear correlations are observed for the two eta(Q) values for Rb2SO4, while eta(Q) decreases parabolically with increasing temperature for RbClO4. The C-Q and eta(Q) parameters for RbNO3 exhibit nonmonotonic variations with temperature. These variations are ascribed to an increase in molecular motions (displacements/reorientations) for the NO3 groups with temperature. For RbClO4, Rb2SO4, and RbNO3 the dependencies of the principal elements of the quadrupole tensors on temperature are evaluated and relationships between these dependencies and variations of structural parameters associated with thermal expansion of the unit cells are discussed. The observed dependencies of C-Q, eta(Q), and delta(iso) on temperature may account for the generally minor discrepancies in these parameters reported in the literature for RbClO4, Rb2SO4, and RbNO3 from NMR experiments at ambient temperatures.
