自1946年物理学家珀塞尔(Purcell)和布洛赫(Bloch)发现核磁共振现象至今仅有四十余年的历史,而化学家利用这一现象来解决化学中的一些问题的历史更短,但目前核磁共振谱已成为化学工作者用来确定分子结构及获
Since 1946 physicists Purcell and Bloch have discovered that the phenomenon of the magnetic resonance (NMR) has only been more than 40 years old, and chemists have used this phenomenon to solve some of the problems of chemistry for a short time , But now NMR spectroscopy has become used by chemists to determine molecular structure and gain
