摘要: 以数种过渡金属的核磁共振研究介绍了有关技术在近年的发展;内容集中于如何从图谱取得化学信息。讨论分为固体谱与液体谱两部分,固体谱会着重谱线的分析,液体谱则集中对有关化学位移的理论解释。

Abstract: This article reviews the recent devefopment of transition metal NMR spectroscopy with the main emphasis on the methodology for the extraction of chemical information.The discussion is divided into two parts.Solid state NMR focuses mainly in the line shape analysis while the solution part concerns with the interpretation of chemical shifts.
