摘要: 本文提出了一个计算次甲基质子NMR化学位移的经验式
δCHXYZ=δ(CH3)2CHZ+△xy
主要用来计算那些Bell、Bowles和Senese关系式不适用的、含有无去屏蔽作用的次甲基质子体系中次甲基质子的化学位移。

Abstract: In this paper the relationship
δCHXYZ=δ(CH3)2CHZ+△xy
is proposed for calculating the chemical shift of melhinc proton in the systems containing less-deshielded methine protons which do not obey the Bell, Bowles, and Senese relationship.
