Introduction

This LEAI-10 experimental system of continuous-wave nuclear magnetic resonance (CW-NMR) consists of a probe, an electromagnet, and a main machine unit. It is easy to use with a high SNR. It is an ideal experimental instrument for advanced physics laboratories.

 

Using this instrument, the following experiments can be performed:

 

1. Understand the classical theory of NMR.

2. Master the experimental method for studying NMR phenomena.

3. Observe NMR absorption signals of H-nuclei and F-nuclei, and measure magnetic field strength.

4. Observe NMR phenomena and determine gyromagnetic ratio, g-factor and nuclear magnetic moment.
