摘　　要：从微量实验到工业生产,有机合成的发展离不开现代分析仪器的使用,特别是核磁共振波谱仪的广泛使用。但在有机反应中难以避免混合物的生成,快速地分析混合物的成分与比例至关重要。使用核磁共振波谱仪可以轻松地解决这一难题,从有机混合物的核磁氢谱中得到的核磁数据可以快速计算出各组分的相对含量。并且在许多高校的仪器分析课程中,核磁一直是课程的重点,但教学与实际使用的衔接不畅,核磁的应用范围较窄。若从实际应用角度理解核磁,更有助于培养学生的化学素养。From micro experiment to industrial production, the development of organic synthesis is inseparable from the use of modern analytical instruments, especially the widespread use of nuclear magnetic resonance spectrometers. It is difficult to avoid the formation of mixtures in organic reactions and it is very important to quickly analyze the composition and proportion of the mixtures. However, the use of nuclear magnetic resonance spectrometer can easily solve this problem. NMR data obtained from ^(1)H NMR spectrum of the organic mixtures can quickly calculate the relative content of each component. And in the instrumental analysis courses of many colleges and universities, nuclear magnetic resonance spectrometers have always been the focus of the course, but the connection between teaching and practical use is not smooth, and the application range of nuclear magnetic resonance spectrometers is relatively narrow. If we understand nuclear magnetism from the perspective of practical application, it will be more helpful to cultivate students’ chemical literacy.
