The theoretical NMR spectrum is compared with proton and fluorine spectra in three single crystals containing pairs of CH 3 or CF 3 groups. The validity of another model, treating each of the triads as a single quasi-quadrupolar particle of spin-12, is discussed....
核磁共振谱(NMR Spectrum)是有机化学中一种常用的分析技术,通过核磁共振现象来研究分子的结构和化学环境。本文将对核磁共振谱的解读与应用进行整理,并重点讨论相关的基础知识点。 一、核磁共振原理及基本概念 核磁共振是指处于外磁场中的核自旋在受到射频辐射激发后产生共振现象。核磁共振仪中的磁场通常使用强磁场产生,...

In Table 2, NMR data are presented that allow the confirmation of a structure. A deceptively simple 1H NMR spectrum, consisting of only three singlets, at 6.53, 7.04 and 8.23 p.p.m., and an ABM system, at 4.39, 3.29 and 3.18 p.p.m., with 5 heteroatoms present makes structure ...
We propose here a new method: ChemSMP (Chemical Shifts to Metabolic Pathways), which facilitates rapid analysis by identifying the active metabolic pathways directly from chemical shifts obtained from a single two-dimensional (2D) [13C–1H] correlation NMR spectrum without the need for ...
