In this work, we measure the spin-lattice relaxation time (T1), spin-spin relaxation rate (T2), resonance linewidth (Δν) and the consequent coherence time of the resonance (𝑇 The data presented here shows that while the BPP model for dipolar interaction of two nuclei is applicable for LiPS5Cl at the Li nuclear resonance frequencies and temperature of our study, the BPP model does not describe the Li NMR relaxation in Li3InCl6, Li3YCl6 and Li1.48Al0.48Ge1.52(PO4)3.
