本文描述高分辨率NMR(核磁共振)波谱仪的旋转边峰效应、它产生的原因及其与磁场梯度的关系,并且根据这些关系在设计上采取有效枝术措施,当应用这种谱仪时,适当调节到正常工作状态,能够排除它。同时给出实验结果。在我国的CH—203型永磁高分辨率NMR波谱仪中采用这种技术,实验上获得第一旋转边峰的高度与样品的NMR波谱主峰高度之比S_1为0.52%;第二、第三旋转边峰可以忽略不计。文章最后部分进行了讨论。
This paper describes the spin-side peak effect of high-resolution NMR (nuclear magnetic resonance) spectrometer, its reason and its relationship with the magnetic field gradient, and according to these relations in the design to take effective measures, when using this spectrometer , Properly adjusted to the normal working condition, to exclude it. At the same time, the experimental results are given. In our country, the CH-203 permanent magnet high-resolution NMR spectrometer used this technique to experimentally obtain the ratio of the height of the first rotation side peak to the height of the main peak of the NMR spectrum of the sample, S 1, is 0.52%. The second and third Side of the rotation can be ignored. The last part of the article is discussed.
