The basic principle and the classification of two-dimensional spectroscopy are briefly introduced, as well as some important concepts; chemical shift correlated spectroscopy (COSY), J-coupling resolved spectroscopy, diagonal peak, self-correlated peak, cross peak (off-diagonal peak).
本文简要介绍了二维谱的基本思想,谱的分类以及常用的一些重要概念:化学位移相关谱(COSY),J耦合分解谱,对角峰,自相关峰,交叉相关峰(非对角峰)。
