Proton transient nuclear Overhauser enhancement (TnOe) and spin-lattice relaxation times (T1) have been used to evaluate the conformations of several monosaccharides and disaccharides containing (13C) and (2H) substitution. Absolute 1H–1H internucl

13C and 19F nuclear magnetic relaxation rates in liquid CFBr3 have been measured at 14.1 kG. By assuming that the motion of the molecules at low temperatures follows the classical diffusion model, the contributions of various relaxation mechanisms ha

19F and 14N nuclear magnetic spin‐lattice relaxation rates in liquid CF3CN have been measured at 14.1 kG. From 14N relaxation rates, the correlation times of the tumbling motion were directly determined. By separating 19F relaxation rates into term

A general program is described which provides a variety of nuclear relaxation measurements on an NMR pulse spectrometer under control of a minicomputer. The common pulse sequences for T1 T2 and T1ρ. are included. A field gradient coil was added to t
