Abstract

Abstract Deuterium spin-lattice relaxation (T 1) data for 3α-deuteriocholesterol and 3β- deuterioepicholesterol in solution were obtained at 12.21 MHz as a function of solvent viscosity (η). The correlation times (τ c) for both 3-deuteriosterols varied in a linear fashion over the range of viscosities studied. The data showed that although both 3α- deuteriocholesterol and 3β-deuterioepicholesterol undergo rapid reorientations (τ c≈ 10− ...
