Nuclear magnetic resonance spectroscopy (NMR) is a technique used for analyzing the chemical properties of molecules. Synonyms for NMR include magnetic resonance spectroscopy, NMR spectroscopy, and spectroscopic magnetic resonance. Nuclear magnetic resonance spectroscopy is commonly used in chemical research to study the structure and properties of molecules, including complex organic compounds, polymers, and biological molecules like proteins and DNA. Additional synonyms for NMR spectroscopy include magnetic resonance imaging (MRI), which uses the same principles as NMR but is applied to medical imaging, and nuclear magnetic resonance imaging (NMRI), which is another term for MRI. Overall, NMR and its synonyms are vital tools for modern chemical and biological research.
