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
