The RMN allows to observe any nucleus with magnetic properties. The fact that the hydrogen nucleus (which is present in most organic compounds) is relatively sensitive to the technique, makes this technique principal for structural determination of organic molecules.
The nuclei are oriented subject to an intense magnetic field generated by a superconductor, selecting the specific pulse frequency for the nuclei we want to examine, these are observed selectively.
Once the frequency is selected, the nuclei can be distinguished from each other by the differences in their magnetic environment within the molecule; that is, its position and its chemical environment.
