NMR spectroscopy requires a strong magnetic field as well as a source of radio frequency (rf) radiation. Here are the steps involved:

1. Sample Preparation: The sample to be studied is prepared and placed in a strong magnetic field. The sample is usually dissolved in a solvent, and then placed in a magnetic field.

2. Alignment of Spins: The strong magnetic field causes the atomic nuclei in the sample to align their spins with the direction of the field.

3. Application of rf Radiation: Radio frequency radiation is then applied to the sample. This causes the nuclei to absorb energy and flip their spins against the magnetic field.

4. Relaxation and Detection: After the rf radiation is turned off, the nuclei return to their original alignment, releasing energy in the process. This energy is detected and recorded.

5. Data Analysis: The recorded data is then analyzed to determine the chemical structure of the sample. The frequency at which the nuclei absorb the rf radiation depends on the strength of the magnetic field and the type of nucleus, providing information about the chemical structure of the sample.
