The feasibility of high-resolution ¹⁷⁵Lu solid-state NMR spectroscopy in intermetallic compounds crystallizing with cubic crystal structures is explored by magic-angle spinning NMR at different magnetic flux densities. The large quadrupole moment of this isotope (3.49 × 10⁻²⁸ m²) restricts observation of the NMR signal to nearly perfectly ordered crystalline samples. Signals are successfully detected and analyzed in the binary pnictides LuPn (NaCl-type structure; Pn = P, As, Sb) and the intermetallic compounds LuPtSb and LuAuSn, both crystallizing with the MgAgAs-type structure. Sources of line broadening are discussed based on field-dependent static and MAS-NMR spectra, providing guidance with respect to measurement conditions resulting in reliable results. The results highlight the importance of ionic/covalent bonding effects for the detectability of the signal, which reduce the probability of real structure effects commonly observed in intermetallic compounds. No ¹⁷⁵Lu NMR signals can be observed in various cubic Heusler compounds. This is attributed to mixed site occupancies and other structural defects producing electric field gradients whose interaction with the ¹⁷⁵Lu quadrupole moments broadens the signal beyond detection.

通过魔角旋转NMR在不同的磁通密度下探索了高分辨率的¹⁷⁵ Lu固态NMR光谱在立方晶结构结晶的金属间化合物中的可行性。该同位素的大四极矩（3.49×10 ^-28 m ²）将NMR信号的观察限制在几乎完美有序的晶体样品中。在二元肽Lu Pn（NaCl型结构；Pn）中成功检测和分析了信号 = P，As，Sb）和金属间化合物LuPtSb和LuAuSn，均以MgAgAs型结构结晶。基于场相关的静态光谱和MAS-NMR光谱讨论了谱线展宽的来源，为获得可靠结果的测量条件提供了指导。结果突出了离子/共价键合效应对于信号可检测性的重要性，这降低了通常在金属间化合物中观察到的实际结构效应的可能性。无¹⁷⁵个NMR信号可以以各种立方霍伊斯勒化合物被观察到。这归因于混合的位置占用和其他结构缺陷，产生电场梯度，这些电场梯度与¹⁷⁵ Lu四极矩的相互作用将信号拓宽到无法检测的程度。
