Multinuclear NMR


Multinuclear magnetic resonance (NMR) is a powerful analytical tool that can provide detailed information about the structure and composition of a wide variety of materials. NMR spectroscopy can be used to determine the types and quantities of atoms present in a sample, as well as the spatial arrangements of those atoms.

Multinuclear NMR spectroscopy is a powerful technique that can be used to obtain detailed structural information about a wide variety of materials. The technique is based on the principle that the nuclei of certain atoms (e.g., 1H, 13C, 15N, 31P) have a spin that can be aligned with an applied magnetic field. When the nuclei are exposed to radiofrequency (RF) radiation, they will absorb energy at a characteristic frequency that is proportional to the strength of the magnetic field.

The RF energy is absorbed by the nuclei and causes them to rotate, or spin, at a rate that is proportional to the applied magnetic field. The nuclei return to their original spin state when the RF radiation is turned off. The process of absorbing and re-emitting RF energy is called resonance.

The frequency of the RF radiation that is absorbed by the nuclei is determined by the strength of the applied magnetic field. The strength of the magnetic field can be varied by changing the current in the coils that produce the field.
