Nuclear magnetic resonance (NMR) is a physical phenomenon in which magnetic nuclei in a magnetic field absorb and re-emit electromagnetic radiation.\[0\] |

Nuclear magnetic resonance builds on the physics concepts of resonance and nuclear spin (angular momentum of elementary particles of an atom). Protons, electrons, atomic nuclei, and other elementary particles have an intrinsic spin as if they were spinning on their axes. When atomic nuclei, or other charged particles, spin they become like a magnetic dipole (like a bar magnet). A nucleus, or elementary particle, possessing spin will wobble or precess when they are placed in a magnetic field. A nucleus in a magnetic field precesses at a frequency, called the Larmor frequency, which is proportional to the magnetic field. When an atom is in a constant magnetic field, it nucleus precesses at the Larmor frequency. If in addition to the constant magnetic field, there is also a weaker perpendicular magnetic field that varies at the same frequency as the Larmor frequency for the nucleus, then the nucleus resonates. The phenomenon is called Nuclear Magnetic Resonance (NMR).\[1\] Figure 1 shows an intuitive model of explanation above. |
