摘要

标量耦合提供了关于分子结构和动力学的重要信息。标量耦合常数的测量是核磁共振波谱学中一个重要的研究课题。然而，由于复杂的信号分裂模式和信号重叠，J值的测量通常不是直截了当的。对于同核和异核情况，已经提出了许多测量标量耦合常数的方法。本文回顾了测量标量耦合常数的不同方法，并介绍了几种应用。标量耦合常数的精确测量对分子结构的解析和分子动力学的研究具有重要意义。

High-resolution methods for the measurement of scalar coupling constants

Scalar couplings provide important information regarding molecular structure and dynamics. The measurement of scalar coupling constants constitutes a topic of interest and significance in NMR spectroscopy. However, the measurement of J values is often not straightforward because of complex signal splitting patterns and signal overlap. Many methods have been proposed for the measurement of scalar coupling constants, both for homonuclear and heteronuclear cases. Different approaches to the measurement of scalar coupling constants are reviewed here with several applications presented. The accurate measurement of scalar coupling constants can greatly facilitate molecular structure elucidation and the study of molecule dynamics.
