•Nuclear magnetic resonance, or NMR as it is abbreviated by scientists, is a phenomenon which occurs when the nuclei of certain atoms are immersed in a static strong magnetic field and exposed to a second oscillating magnetic field in the form of radiofrequency pulses, it is possible to transfer energy into the spin system and change the state of the system. After the pulse, the system relaxes back to its state of equilibrium, sending a weak signal that can be recorded.
