What is NMR?
- Nuclear Magnetic Resonance (NMR) spectroscopy is an analytical chemistry technique used in quality control and research for determining the content and purity of a sample as well as its molecular structure.
- For example, NMR can quantitatively analyze mixtures containing known compounds.
- For unknown compounds, NMR can either be used to match against spectral libraries or to infer the basic structure directly.
- Once the basic structure is known, NMR can be used to determine molecular conformation in solution as well as studying physical properties at the molecular level such as conformational exchange, phase changes, solubility, and diffusion.
