Nuclear magnetic resonance
Nuclear magentic resonance is a powerful technique which involves placing nuclei within an external magnetic field enabling thus them to undergo precession. The 'resonance' part of the names implies the fact that a second (usually perpendicular) radiofrequency pulse tuned to the precessional fre...
Energy difference between spin up and spin down states
The energy difference between spin up and spin down states of hydrogen are important in understanding net magnetisation vector of tissue for magnetic resonance imaging. Each hydrogen atom is formed by one proton and one orbiting electron. Because the atomic number is 1, it has a spin quantum nu...
