Abstract

Laplace nuclear magnetic resonance (NMR), dealing with NMR relaxation and diffusion experiments, reveals details of molecular motion and provides chemical resolution complementary to NMR spectra. Laplace NMR has witnessed a great progress in past decades due to the development of methodology and signal processing, and it has lots of extremely interesting applications in various fields, including chemistry, biochemistry, geology, archaeology, and medicine. The aim of this minireview is to give a pedagogically oriented overview of Laplace NMR. It does not provide a full literature review of the field, but, instead, it elucidate the benefits and features of Laplace NMR methods through few selected examples. The minireview describes also recent progress in multidimensional Laplace NMR and Laplace inversion methods. Furthermore, the potential of modern hyperpolarization methods as well as ultrafast approach to increase the sensitivity and time-efficiency of the Laplace NMR experiments is highlighted.

摘要

拉普拉斯核磁共振(NMR)涉及NMR弛豫和扩散实验,揭示了分子运动的细节,并提供了与NMR光谱互补的化学分辨率。由于方法学和信号处理的发展,拉普拉斯NMR在过去几十年中取得了巨大进展,并且在包括化学、生物化学、地质学、考古学和医学在内的各个领域都有许多极其有趣的应用。本微型综述的目的是对拉普拉斯NMR进行面向教学的概述。它没有提供该领域的完整文献综述,而是通过几个选定的例子阐明了拉普拉斯NMR方法的优点和特点。该微型综述还描述了多维拉普拉斯NMR和拉普拉斯反演方法的最新进展。此外,还强调了现代超极化方法以及超快方法在提高拉普拉斯NMR实验的灵敏度和时间效率方面的潜力。
