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,
29Si and 13C spin-lattice relaxation times and the corresponding nuclear Overhauser enhancements have been measured for Ph,SiH,\_, (n = 1,2, 3), for Ph,SiHMe and for Ph,SiCl, . Thence dipolar and other contributions to the relaxation rates have been separated. The dipolar rates are used to discuss i
