我们在前文曾对ABC三自旋质子磁共振谱的标划归属提出了一个新的方法。在另一篇文章中,用核磁共振谱鉴定了2-氯-6-(三氯甲基)吡啶的化学结构。本文则根据我们提出的新方法对2-氯-6-(三氯甲基)吡啶的核磁共振谱进行归属,并在此基础上计算了它的化学位移和偶合常数。因此,本文既是前文理论的一个验证,也是第一次得到2-氯-6-(三氯甲基)吡啶核磁共振的有关分子参数。图1、图2分别是2-氯-6-(三氯甲基)吡啶的60兆赫和90兆赫的核磁共振谱图。表1列出了各谱线的相对位置和相对强度。
We have previously proposed a new method for the assignment of ABC tri-spin proton magnetic resonance spectra. In another article, the chemical structure of 2-chloro-6- (trichloromethyl) pyridine was identified by nuclear magnetic resonance spectroscopy. In this paper, the NMR spectra of 2-chloro-6- (trichloromethyl) pyridine are assigned according to the new method proposed by us, and its chemical shifts and coupling constants are also calculated. Therefore, this paper is not only a verification of the previous theory, but also the first time to get 2-chloro-6- (trichloromethyl) pyridine nuclear magnetic resonance related molecular parameters. Figure 1 and Figure 2 show the 60 MHz and 90 MHz NMR spectra of 2-chloro-6- (trichloromethyl) pyridine, respectively. Table 1 lists the relative positions and relative intensities of the respective lines.
