Ultraslow Diffusion in Polycrystalline h-LiTiS₂ Studied by ⁷Li Spin-Alignment Echo NMR Spectroscopy

Abstract:

Multiple-time spin-alignment echo (SAE) NMR spectroscopy of spin- 3 2 nuclei is used to study ultraslow diffusion in the hexagonal layered Li ion conductor LixTiS2 (x  1). Two-time correlation functions were monitored by recording (Jeener-Broekaert) echo amplitudes for constant evolution and variable mixing times. Echo decay rates t
