Nuclear magnetic resonance spectroscopy ( abbreviated as NMR spectroscopy), has become the preeminent technique for determining the structure of organic compounds over the past fifty years. The NMR spectroscopy can be used to to determine the carbon-hydrogen framework of a molecule and works with even the most complex molecules, to study mixtures of analytes, to understand dynamic effects such as change in temperature and reaction mechanisms. It is an invaluable tool in understanding protein and nucleic acid structure and function. Among all spectroscopic methods, the NMR spectroscopy is the only one for which a complete analysis and interpretation of the entire spectrum is normally expected.
