Abstract

2H nuclear spin-lattice relaxation has been investigated in several glass-forming liquids: (a) fully deuterated ortho-terphenvl, (b) selectively deuterated glycerols, namely glycerol-d3 (O-2H bonds) and glycerol-d5 (C-2H bonds), and (c) LiCl-42H2O. The experiments have been performed at deuteron resonance frequencies of 55MHz (≙8.5T) and 33MHz (≙ 5.1 T) covering a wide temperature range around the calorimetric glass transition temperature Tg.
