Nuclear Magnetic Resonance
Nuclear magnetic resonance (NMR), as abbreviated by scientists is a phenomenon occurring when nuclei of some given atoms are immersed in a static magnetic field while at the same time being exposed to second vibrating magnetic field. While some nuclei may experience this phenomenon others do not depending on if they posses spin property. Most of the matters that one can examine with nuclear magnetic resonance are composed of molecules while molecules are composed of atoms. The proton has a basic property known as spin which can be thought of as a small magnetic field responsible for causing production of NMR signal by a nucleus. It should be clear that its not all nucleus that are capable of possessing the spin property (Haner & Keifer, 2009).
All the stable nuclides containing odd numbers of proton and neutron have angular momentum and intrinsic magnetic moments. That means they have a non zero spin, on the other hand,   all the nuclides that have an even number of protons and neutrons have spin of 0. Some of the most commonly studied nuclei include: 1H, this is the second most sensitive NMR isotope from the radioactive 3H (Hornak, 2002).
When the nuclear magnetic moment that is associated with a spin of nuclear is positioned in an exterior magnetic field, the diverse spin states are given different magnetic latent energies. In the existence of the inert magnetic field which generates a small amount of spin polarization, an RF signal of the appropriate frequency can stimulate a transition linking spin states. This spin flip locates some of the spins in their elevated energy state. If the RF signal is then switched off, the relaxation of the spins rears to the lower state generating a measurable amount of radio frequency signal at the resonant frequency which is associated with the spin flip. The magnetic dipole moment, also called magnetic moments, which exist in magnetic field, have a latent energy that is related to its orientation...
