近20年来,磁共振谱在化学方面的应用是愈来愈广泛了。与光谱法比较,磁共振谱这一方法具有很多特点。首先是磁共振谱的作用能量较小,而频率位于较红外线更长的区域,因而可以获得电子及核在其自旋态能阶之间的跃迁知识。其次是从磁偶合规律可以确定核及电子所处的环境,以及它们之间的相互作用本性。最后是从核及电子之间的偶合区域推测电子的
In the past 20 years, the application of magnetic resonance spectroscopy in chemistry has become more and more widespread. Compared with the spectrometry, the method of magnetic resonance spectroscopy has many characteristics. The first is that the energy of the magnetic resonance spectrum is small and the frequency is in a region longer than the infrared, so that the knowledge of transitions between electrons and nuclei at their spin-order energy levels can be obtained. Followed by the law of magnetic coupling can determine the nuclear and electronic environment, as well as the nature of the interaction between them. The last is the speculation of electrons from the coupling between nuclear and electronic fields
