Abstract

Proton spin-lattice relaxation times in Ca(NH₃)₆ have been measured between 10 and 125 K. Three distinct T₁ minima have been observed and are attributed to NH₃ diffusion and to NH₃ rotating in two different hindering potentials. The results suggest that there is an appreciable difference in molecular structure between NH₃ and ND₃ in this compound.
