介绍了分析运动效应对~2H核磁共振固体谱线形状影响的方法。给出了固体中各向异性运动的几个简单模型，并由此计算了线形和松弛实验。利用这些方法可以显式地求出快速极限谱的序参数。这些方法被扩展到包括根据特定运动模型的中间交换光谱的分析。描述了交换展宽引起的微分T2‘S效应对粉末线形的影响。给出了快速和中间交换条件下粉末部分弛豫谱中T1各向异性的计算和分析方法。
Methods for the analysis of motional effects on 2H NMR solid state line shapes are described. Several simple models of anisotropic motions in solids are presented from which line shapes and relaxation experiments are calculated. Using these methods order parameters of fast limit spectra can be explicitly evaluated. These methods are extended to include analysis of intermediate exchange spectra in terms of specific motional models. The effects of differential T2’s arising from exchange broadening on the line shape in powders are described. Methods for the calculation and analysis of T1 anisotropy in partially relaxed spectra of powders for both fast and intermediate exchange regimes are presented.
