核磁共振波谱是应用核物理学原理,借助电子技术来研究分子结构的一种重要的技术方法。核磁共振现象是Bloch(斯坦福大学)和Purcell(哈佛大学)在1946年同时发现的,为此,1952年他们获得诺贝尔奖金。 发现核磁共振之后,开始阶段确定了布洛赫(Bloch)方程、弛予理论、范弗莱克矩法等基本原理:1951年后,发现了化学位移和谱线分裂,开始了对有机官能团以及对金属奈特位移的研究,在1955年前后造出了分辨率为10~(-7)—10~(-9)的谱仪,极大的促进了化
Nuclear magnetic resonance spectroscopy is the application of nuclear physics principles, using electronic technology to study the molecular structure of an important technical method. The phenomenon of nuclear magnetic resonance was discovered both by Bloch (Stanford) and Purcell (Harvard University) in 1946, for which they won the Nobel Prize in 1952. After the discovery of the nuclear magnetic resonance, the Bloch equation, the relaxation theory, the Van Fleck moment method, and other basic principles were identified at the beginning: after 1951, chemical shifts and spectral splitting were found, and organic functional groups, The study of the displacement of the metal Knight made a spectrometer with a resolution of 10 -7 -7 -10 -9 before and after 1955,
