本文对核磁共振(NMR)方法研究分子结构、特别是分子动力学问题进行了概述。由于分子中存在许多对磁场的“定域敏感元”,所以NMR可以提供分子结构及分子运动的信息,这是NMR方法的一个突出特征。过去十年中,一些有效的研究分子结构的方法已发展成熟。COSY和NOESY的结合以及由此发展出来的其它方法已成为研究生物大 In this paper, the molecular structure, especially the molecular dynamics, are reviewed by NMR. Because there are many “localized sensing elements” in the molecule that are magnetic fields, NMR can provide molecular structure and molecular motion information, which is a prominent feature of the NMR method. In the past decade, some effective methods of studying the molecular structure have matured. The combination of COZY and NOESY and other methods developed thereby has become a research biology
