Nuclear Magnetic Resonance (NMR) Spectroscopy is an advanced analytical technique used to determine the structure, dynamics, and interactions of molecules. It works by placing a sample in a strong magnetic field and exposing it to radiofrequency radiation, which excites the nuclei of certain atoms (commonly hydrogen or carbon). The way these nuclei absorb and re-emit energy provides detailed information about the chemical environment and arrangement of atoms within the molecule. NMR is one of the most powerful tools in chemistry and biochemistry, allowing researchers to identify unknown compounds, confirm molecular structures, study protein folding, and analyze complex mixtures. Because it is non-destructive and highly precise, NMR spectroscopy is widely applied in pharmaceuticals, biotechnology, materials science, and medical imaging (MRI being a direct application of the same principle).
