自从物理学家发现核磁共振(NMR)有化学位移,从而使NMR进入了有机化学实验室,到现在已有三十年了。早期,最常见的是高分辨~1H谱。70年代以后,由于引入了PFT技术,NMR灵敏度低的困难已经解决了,因此,测定低丰度核的工作受到广泛重视,其中最重要的是~(13)C。自从有了PFT的商品仪器,~(13)C NMR工作蓬勃开展,文献急剧增加,可以认为:~(13)C与~1H NMR相辅相成,是目前有机化学家手中最强有力的武器。我国建立NMR技术已有十多年的历史,~(13)C方面也有了不少工作。到目前为止,介绍~(13)C谱基础知识的资料还十分少,为此,我们编译了德同化学家von E.Breitmaier及G.Bauer所著的《~(13)C NMR Spektroskopie》一书,并选译部分练习题,以供有机化学工作者参考。本文将以连载方式在本刊载出。限于编译者的水平,错误难免,请批评指正。
It has been 30 years since physicists discovered that NMR has been chemically shifted to allow NMR to enter organic chemistry laboratories. Early, the most common is the high resolution 1H spectrum. Since the 1970s, due to the introduction of PFT technology, the difficulty of low sensitivity of NMR has been solved. Therefore, the work of measuring low abundance nuclei has received much attention. The most important one is ~ (13) C. Since the commercialization of PFT instruments, ~ (13) C NMR has been vigorously carried out and the literature has been drastically increased. It can be concluded that ~ (13) C complements ~ 1H NMR and is the most powerful weapon currently available to organic chemists. Our country has established NMR technology for over ten years, and a lot of work has been done in ~ (13) C aspect. So far, the information on the basic knowledge of ~ (13) C spectrum is still very few. Therefore, we compiled the “~ (13) C NMR Spektroskopie” by De Tong chemists von E. Breitmaier and G. Bauer Book, and choose some translation exercises for organic chemical workers reference. This article will be serialized in our magazine. Limited to the compiler’s level, the mistake is inevitable, please criticize correction.
