<unk>  most commonly known as<unk>  is the name given to the technique which exploits the<unk>  properties of certain nuclei. The most important applications for the organic chemist are proton<unk>  and carbon-13<unk> .  In principle,<unk>  is applicable to any nucleus possessing spin.
Many types of information can be obtained from an<unk>  spectrum. Much like using infrared spectroscopy to identify functional groups, analysis of a 1D<unk>  spectrum provides information on the number and type of chemical entities in a molecule.
The impact of<unk>  on the natural sciences has been substantial. It can, amongst other things, be used to study mixtures of analytes, to understand dynamic effects such as change in temperature and reaction mechanisms, and is an invaluable tool in understanding protein and nucleic acid structure and function. It can be applied to a wide variety of samples, both in the solution and the solid state.
