H Nuclear Magnetic Resonance (INMR)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.
