Most stable isotopes have a nuclear spin >1/2, but the quadrupole interaction poses challenge on their detection by nuclear magnetic resonance (NMR). On the other hand, the quadrupole interaction is a rich source of structural information that may be exploited for solution NMR in the form of residual quadrupolar couplings (RQCs) of weakly oriented samples. While H RQCs are now well established for structure verification and enantiomeric discrimination of organic molecules, we will in this article highlight some recent work on RQCs of other nuclei (especially Li and B).
大多数稳定同位素具有大于1/2的核自旋，但四极相互作用对通过核磁共振（NMR）检测它们构成挑战。另一方面，四极相互作用是丰富的结构信息来源，可通过弱取向样品的剩余四极耦合（RQC）形式用于溶液NMR。虽然H RQC现在已广泛用于有机分子的结构验证和对映体鉴别，但在本文中，我们将重点介绍一些关于其他原子核（特别是Li和B）的RQC的最新研究工作。
