本文叙述再生式核磁共振波谱仪的原理,安装和试验结果.被观察的样品可以是固体或液体[气体样品在具有足够浓度时(相当于室温中十大气压以上)也可以观察]它可以用来研究物体内的原子核的磁共振现象,波谱仪工作的频率在30兆周附近,使用恒定磁场为7000高斯,一般用来观察氢和氟原子核的磁共振讯号,仪器的工作频率范围加以改变以后,可以用来观察其他原子核的共振讯号.也可以用来精确测量一定范围内的磁场强度,当磁场强度的范围较大时,仪器工作频率的可调范围需要相应的增大.
This article describes the principles, installation, and test results of a regenerative NMR spectrometer. The sample to be observed can be either solid or liquid [gas samples are also observable with sufficient concentration (equivalent to ten atmospheres or more at room temperature)] The magnetic resonance phenomenon of the nucleus of the object is studied. The frequency of the spectrometer is around 30 trillion cycles, and the constant magnetic field is 7000 Gauss. Generally, the magnetic resonance signal of hydrogen and fluorine atomic nucleus is observed. After the working frequency range of the instrument is changed, Can be used to observe the resonance of other nuclei signal can also be used to accurately measure the magnetic field strength within a certain range, when the magnetic field intensity range, the adjustable range of the instrument operating frequency needs to be increased accordingly.
