Nuclear Magnetic Resonance (NMR) spectroscopy is a powerful analytical technique used to determine the structure and dynamics of molecules. It relies on the absorption and re-emission of electromagnetic radiation by nuclei in a magnetic field. This method provides insights into the arrangement of atoms, functional groups, and the connectivity within molecules. Advanced NMR techniques, including 2D-NMR and solid-state NMR, further enhance the understanding of complex and non-liquid samples.
