Abstract

The proton and phosphorus dynamics of the superprotonic conduction in the LiH₂PO₄ system has been studied by means of ¹H and ³¹P NMR rotating-frame nuclear magnetic resonance (NMR). The temperature-dependent ¹H NMR rotating-frame spin-lattice relaxation time measurements revealed in a sensitive manner the evolution of the microscopic environment and proton dynamics of the two distinct hydrogen-bond types in the system, which is quite compatible with the electrical conductivity and the impedance spectroscopy measurements. Besides, the proton dynamics was found to be coupled to the reorientational motion of the PO₄ tetrahedra.
