The 29Si spin-lattice relaxation times, &(%), of the various silicate anions present in high-purity alkaline silicate solutions are reported. Regular silicate cages display the longest T,(29Si) values and, in the case of the cubic octamenc cage, an unexpectedly large nuclear Overhauser enhancement,
