This review presents recent developments in the application of NMR spectroscopic techniques in the study of ionic liquids. NMR has been the primary tool not only for the structural characterization of ionic liquids, but also for the study of dynamics. The presence of a host of NMR active nuclei in ionic liquids permits widespread use of multinuclear NMR experiments. Chemical shifts and multinuclear coupling constants are used routinely for the structure elucidation of ionic liquids and of products formed by their covalent interactions with other materials. Also, the availability of a multitude of NMR techniques has facilitated the study of dynamical processes in them. These include the use of NOESY to study inter-ionic interactions, pulsed-field gradient techniques for probing transport properties, and relaxation measurements to elucidate rotational dynamics. This review will focus on the application of each of these techniques to investigate ionic liquids.

本综述介绍了 NMR 光谱技术在离子液体研究中应用的最新进展。核磁共振不仅是离子液体结构表征的主要工具，也是动力学研究的主要工具。离子液体中存在大量 NMR 活性核允许广泛使用多核 NMR 实验。化学位移和多核耦合常数通常用于离子液体和由它们与其他材料共价相互作用形成的产物的结构解析。此外，大量 NMR 技术的可用性促进了对其中动力学过程的研究。其中包括使用 NOESY 研究离子间相互作用、用于探测传输特性的脉冲场梯度技术、和弛豫测量以阐明旋转动力学。本综述将重点关注这些技术中每一种在离子液体研究中的应用。
