Nuclear Magnetic Resonance (NMR) is a powerful analytical technique used to determine the structure of molecules. It works by applying a strong magnetic field to a sample, causing certain nuclei, such as hydrogen or carbon, to resonate at specific frequencies. This resonance provides detailed information about the molecular environment, allowing scientists to infer structural details. NMR is widely used in chemistry and biochemistry for analyzing complex mixtures and studying molecular dynamics. Additionally, it plays a crucial role in medical imaging, particularly in MRI (Magnetic Resonance Imaging), which helps visualize internal structures of the body non-invasively.
