13C relaxation data obtained at three different magnetic fields, 9.4, 11.8 and 14.1 T, and at two temperatures, 303 and 318 K, are reported for the pentasaccharide p The pentasaccharide consists of two disaccharide units, attached at positions 2 and 6 to the central mannopyranoside residue. The rel
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
