Abstract

The possibility of retrieving parameters for the combined effect of quadrupole coupling and small chemical-shielding anisotropies from single-crystal NMR of the central transition for half-integer quadrupolar nuclei has been successfully investigated, Rb-87 single-crystal NMR of RbClO4 and Rb2SO4 serve as two properly chosen and illustrative examples, Thereby, discrepancies between some of the Rb-87 parameters recently reported for these two interactions in powders of RbClO4 and Rb2SO4, and determined from MAS and static powder NMR, have been clarified, The orientations of the crystallographic axes for the two rubidium crystals have been predicted by the NMR results and verified independently by XRD analysis.
