Nuclear magnetic resonance (NMR) is a scientific technique used to observe the magnetic properties of atomic nuclei. When placed in a strong magnetic field, certain nuclei resonate at specific frequencies, allowing scientists to gather information about the structure and dynamics of molecules. This method is widely used in chemistry and biochemistry for analyzing complex compounds. NMR is particularly valuable in medical imaging, where it forms the basis of magnetic resonance imaging (MRI). In this context, NMR helps create detailed images of organs and tissues, aiding in the diagnosis of various medical conditions without the need for invasive procedures.
