Abstract

14N NMR of magnetically oriented microcrystals is reported. With a home-built 1H–13C–14N probe capable of modulating the rotation of the sample around the axis normal to the magnetic field, magnetically oriented microcrystal suspension (MOMS) of l-alanine is made. 14N NMR spectra acquired with various timings during intermittent rotation lead to a rotation pattern of the MOMS similar to that of a single crystal. The effect of orientational distribution of the microcrystals to broadening of the resonance line is discussed.

磁定向微晶的 14N NMR
报告了磁定向微晶的 14N NMR。利用自制的 1H-13C-14N 探针(该探针能够调节样品绕磁场法线轴的旋转),制备了 l-alanine 的磁定向微晶悬浮液(MOMS)。在间歇旋转过程中,以不同的时间采集 14N NMR 光谱,结果发现 MOMS 的旋转模式与单晶类似。讨论了微晶的取向分布对共振线增宽的影响。
