| Abstract: | In this contribution we present studies on the mechanism of ion transport in crystalline solid electrolytes employing a range of different solid state nuclear magnetic resonance (NMR) experiments. The first part is devoted to the elucidation of a possible correlation of cation transport and anion reorientation in the dynamically disordered rotor phases of alkali trifluoromethane sulfonates MCF3SO3 (M = Li, Na) employing 7Li, 13C, 17O and 23Na NMR line shape analysis, whereas the second part focuses on the tracking of cation diffusion pathways in the hexaoxometalate Li7TaO6 utilizing 6Li 1D and 2D exchange MAS NMR approaches. |
