What's Nuclear Magnetic Resonance (NMR)? How Does It Work? What's It Used For? A Brief Introduction.

What is Nuclear Magnetic Resonance (NMR) spectroscopy? The NMR spectroscopy is an information-rich, non-destructive analytical technique that provides detailed information about molecular structure, dynamic processes and allows the direct observation of chemical reactions. How does it work? NMR spectroscopy uses the inherent magnetic properties of specific atomic nuclei to reveal the structure, identity, concentration, and behaviour of molecules in solid or liquid samples. NMR relies on a property of certain atomic nuclei that causes them to absorb, then re-release, electromagnetic energy at characteristic frequencies. Shifts in the usual response frequency for a given isotope provide information about their immediate environment, including influences from nearby electrons and magnetic nuclei, making it possible to infer molecular identity, geometry, and more. Where is NMR used and for what reasons? Applications of NMR spectrometry span R&D and quality control for the chemical, environmental, petrochemical, pharmaceutical, and food and beverage industries. NMR fills essential research and clinical needs in biomedicine, proteomics, metabolomics, and more. NMR spectrometers range from cost-conscious benchtop systems to sophisticated research spectrometers with high-field magnets to maximize sensitivity and resolution.
