## Abstract

$^1H$ spin-lattice relaxation time $T_1$ at 15 MHz and 300 MHz, spin-lattice relaxation time in the rotating frame $T_1\rho$ and the spin-spin relaxation time T2 have been measured as functions of temperature for the fast protonic conductor $(NH_4)_4Fe(CN)_6•1.5H_2O$. The minima observed in the $T_1$ dependence on temperature are attributed to the reorientational motions of the $NH_4$ groups while translational diffusion is concluded to dominate the $T_1\rho$ processes.
