Nuclear Magnetic Resonance (NMR) is a powerful analytical technique used to determine the structure and dynamics of molecules. It involves the interaction of nuclear spins with an external magnetic field and radiofrequency pulses, resulting in the emission of electromagnetic signals that can be translated into detailed information about molecular structures.
In the context of
nanotechnology, NMR plays a critical role in characterizing nanomaterials, understanding their properties, and optimizing their functionalities. The ability to analyze molecular structures at the nanoscale is essential for the development of advanced materials, drug delivery systems, and other nanoscale applications.
