Nuclear Magnetic Resonance Spectroscopy

NMR Spectroscopy enables researchers to determine the basic structure of a molecule, the interactions between molecules, and the composition of a given sample. An NMR spectrometer consists of a magnet, a radio-frequency transmitter, and a detector that picks up the rf signal. The principle behind NMR exploits the fact that most nuclei have spin and all are electrically charged and by applying an external magnetic field, an energy transfer is possible from a ground state to a higher one. This transfer takes place at a wavelength corresponding to a radio-frequency, and when the spin relaxes, energy is emitted at the same frequency. NMR spectroscopy is a complimentary technique for other structural and analytical research such as X-ray crystallography, mass spectrometry, electron paramagnetic resonance spectroscopy, and many others. NMR has the advantage that it allows for non-destructive and measurable study of molecules in solution and solid state.
