✦ Synopsis

The Zeeman spin-lattice relaxation is measured in a single crystal and in powdered samples of lithium acetate (CH3COOLi-2D20). Measurements have also been performed in powdered samples of lithium acetate which contain 50% and 95% of CD3-groups besides the CH3-groups. A non-exponential behaviour, i.e. time dependence, of the Zeeman spin-lattice relaxation is clearly observed at temperatures above the Tl-minimum in all samples. The results are explained within the framework of the symmetry-restricted spin-diffusion model of Emid and Wind.
