Respuesta :
proton NMR is a technique that uses nuclear magnetic resonance to study the hydrogen atoms in a sample.
NMR stands for nuclear magnetic resonance, which is the selective absorption of very high-frequency radio waves by specific atomic nuclei when they are exposed to a sufficiently strong stationary magnetic field. The physicists Felix Bloch and Edward M. Purcell independently made the first observation of this phenomenon in 1946.
An analytical chemistry method known as nuclear magnetic resonance (NMR) spectroscopy is used in quality control and research to ascertain a sample's composition and purity as well as its molecular structure. NMR, for instance, can quantitatively assess mixtures containing known substances. In order to understand molecular physics, crystals, non-crystalline materials, and organic molecules in solution, nuclear magnetic resonance spectroscopy is frequently used. NMR is frequently employed in cutting-edge medical imaging methods.
