Nuclear Magnetic Resonance: a non-destructive analytical technique!

 | Post date: 2021/08/23 | 
Nuclear Magnetic Resonance (NMR) is a spectroscopic technique that allows the analysis of three-dimensional structures and dynamics of macromolecules, as well as their complexes in solution, at atomic resolution. This non-destructive analytical technique which was discovered in 1945, consists of a superconducting magnet, a spectrometer, a control system, and a detector (probe). During NMR measurements, a sample solution is placed in the magnetic field and is irradiated with radio waves from a spectrometer that includes observation and irradiation systems. The bounced analog signal, called free induced decay, is amplified and digitized to obtain the corresponding NMR signals and spectrum.
NMR spectroscopic technique is one of the more sophisticated and authenticated techniques used to elucidate the structural characteristics of nanomaterials, polymers, and their nanocomposites. Multinuclear NMR spectral analyses, especially by solid state NMR studies, provide the conformation of different chemical environments for protons, carbons, nitrogen, silicon, etc.
