Nuclear Magnetic Resonance (NMR) Spectroscopy
Introduction:
Nuclear magnetic resonance spectroscopy (NMR) is the most powerful tool available for organic structure determination. Like IR spectroscopy, NMR can be used with a very small sample, and it does not harm the sample. The NMR spectrum provides a great deal of information about the structure of the compound, and some structures can be determined using only the NMR spectrum. More commonly, however, the NMR spectrum is used in conjunction with other forms of spectroscopy and chemical analysis to determine the structures of complicated organic molecules.
NMR is used to study a wide variety of nuclei, including 1H, 13C, 15N, 19F, and 31P. Organic chemists find proton (1H) and carbon-13 (13C) NMR to be most useful because hydrogen and carbon are major components of organic compounds.
Historically, NMR was first used to study protons (the nuclei of hydrogen atoms), and proton magnetic resonance (1H NMR) spectrometers are the most common. "Nuclear magnetic resonance" is assumed to mean "proton magnetic resonance" unless a different nucleus is specified.
