Nuclear Magnetic Resonance Spectrometry, like infrared, visible, and ultraviolet spectrometry is a form of absorption spectrometry. Certain nuclei can absorb electromagnetic radiation in the radiofrequency range. These nuclei are able to absorb this energy because they “spin” about their center axis generating a dipole along it. Protons are among those nuclei that absorb radiofrequency energies. If a proton is placed in a magnetic field its dipole can be in one of two possible orientations. It can be in a low energy state aligned with the field, or a high energy state, a spinning proton will process about an axis at a particular frequency (Figure 1).
