The magnetic interactions between the nuclear magnetic moment and the magnetic moment of unpaired electron(s) depend on the structure and dynamics of the molecules where the paramagnetic center is located and of their partners. The long-range nature of the magnetic interactions is thus a reporter of invaluable information for structural biology studies, when other techniques often do not provide enough data for the atomic-level characterization of the system. This precious information explains the flourishing of paramagnetism-assisted NMR studies in recent years. Many paramagnetic effects are related to the magnetic susceptibility of the paramagnetic metal. Although these effects have been known for more than half a century, different theoretical models and new approaches have been proposed in the last decade. In this review, we have summarized the consequences for NMR spectroscopy of magnetic interactions between nuclear and electron magnetic moments, and thus of the presence of a magnetic susceptibility due to metals, and we do so using a unified notation.

基于磁化率和顺磁性的核磁共振

核磁矩与未配对电子的磁矩之间的磁相互作用取决于顺磁中心所在的分子及其伙伴的结构和动力学。因此，当其他技术通常无法为系统的原子级表征提供足够的数据时，磁相互作用的长程性质是结构生物学研究的宝贵信息的报告者。这些宝贵的信息解释了近年来顺磁辅助 NMR 研究的蓬勃发展。许多顺磁效应与顺磁金属的磁化率有关。尽管这些影响已经为人所知半个多世纪，但在过去十年中已经提出了不同的理论模型和新方法。在这次审查中，
