摘要: 本文采用反转回复法(180°-τ-90°-Τ)n脉冲序列测定了N-正丁基苯胺在两种温度下,各13C核总的自旋-晶格弛豫时间T1和NOE因子ηс值,通过计算估计了各种弛豫机理的贡献大小,并求出了分子无规则运动的相关时间τс,进一步讨论了此分子的动力学状况。

Abstract: The 13C total spin-lattice relaxation times and the NOE factors ηс of N-butyl aniline were measured at two temperatures by means of inversion recovery pulse sequences (180°-τ-90°T).The contributions of each relaxation mechanism were appreciated by calculation, the correlation times τс of molecular random movements were deduced, and the dynamic situation of the molecules was discussed.
