Spin-alignment (Li) spectroscopy was proposed as a nuclear magnetic resonance technique for the study of slow translational motions in solid and solid-like ionic conductors. Phase-cycling permitted the measurement of 2-time translational correlation functions via the generation of a pure quadrupolar ordered state. The correlation functions of the crystalline electrolyte were recorded for times ranging from about 0.1ms to more than 10s; thus implying that translational diffusion coefficients of less than 10 to 20m2/s were accessible.
