摘要
用永久磁铁作为外场的核磁共振实验仪观察共振吸收信号和测量1H、19F的g因子时,如果仪器没有处于最佳状态,将找不到清晰的共振信号。如何对仪器进行适当的调整和技术处理,得到清晰的核磁共振吸收信号,本文对几个相关问题作了探讨和说明。
In nuclear magnetic resonance, using permanent magnet as an external magnetic field, we can observe the nuclear resonant signal and determine the g factor of ~1H and ~(19F. If the instrument is not at the best working state, clear resonant signal will not appear. This paper mainly discussed several methods to obtain distinct nuclear magnetic resonant signals.
