Intermetallic compounds are of broad interest for solid state chemists, condensed matter physicists, and material scientists due to their intriguing crystal chemistry, their physical properties, and their potential applications, ranging from lab curiosities to everyday objects. To characterize and understand the properties of new compounds and novel materials, the availability of structural information, particularly single-crystal X-ray diffraction data, is a mandatory prerequisite. Especially when it comes to the formation of compounds with deficient or mixed site occupancies, superstructures, or representatives crystallizing in other, thus far unknown structure types, a complementary method for structural analysis is of great value. Solid state nuclear magnetic resonance spectroscopy has been a valuable tool in many areas of chemistry, being an element-selective, site-specific, and inherently quantitative tool for detailed structural characterization. Magic-angle spinning conditions eliminate or reduce the effect of anisotropic interactions in the solid state, producing high-resolution spectra.

²⁷ Al固态NMR光谱表征金属间化合物。

金属间化合物因其有趣的晶体化学，其物理性质以及其潜在的应用（从实验室好奇心到日常物品）而吸引了固态化学家，凝聚态物理学家和材料科学家的广泛兴趣。为了表征和理解新化合物和新型材料的特性，结构信息（尤其是单晶X射线衍射数据）的可用性是必不可少的先决条件。特别是当涉及形成具有不足或混合的位点占用，上层建筑或在其他迄今未知的结构类型中结晶的代表的化合物时，一种互补的结构分析方法非常有价值。固态核磁共振波谱已成为许多化学领域中的宝贵工具，是用于详细结构表征的元素选择，针对特定地点且本质上是定量的工具。幻角旋转条件消除或减少了固态各向异性相互作用的影响，从而产生了高分辨率的光谱。
