一、前言自1945年勃洛赫(F.Bloch)及柏赛尔(E.M.Purcèll)提出核磁共振谱以来,这门新颖技术发展很快,尤其在有机化学结构鑑定方面的应用更是推陈出新。它在有机药物、颜料、激素、高分子等等实际分析方面均可用以鑑定组成和基团。有时还可进行高分子结晶度和化合物含水量的测定。其他尚有很多长期以来未曾解决的课题在应用核磁共振谱之后获得了部分解决,或者完全解决。在后面所列的参考书中这些例子是不胜枚举的,因而目前在有机结构研究中它与红外光谱是并驾齐驱的,所以推广这门技术的意义非常重大。
I. INTRODUCTION Since NMR spectroscopy was first proposed by F. Bloch and E.M. Purcèll in 1945, this novel technique has developed rapidly. In particular, its application in the identification of organic chemical structures is even more revolutionary. It can be used to identify components and groups in practical analysis of organic drugs, pigments, hormones, polymers and the like. In some cases, the degree of crystallinity of the polymer and the water content of the compound can be measured. Others There are many longstanding issues that have been partially resolved or completely resolved by the application of NMR spectroscopy. In the references listed later, these examples are too numerous to enumerate. So far in the study of organic structure it is in line with infrared spectroscopy. Therefore, the significance of popularizing this technology is very significant.
