Nuclear magnetic spin alignment
WebThis is called precession. Spinning protons are like spinning-tops spinning about their axis. Precession corresponds to the gyration of the rotating axis of a spinning body about an intersecting axis . The resonance frequency, called Larmor frequency (ω0) or precessional frequency, is proportional to the main magnetic field strength: ω0 = γ B0. http://hyperphysics.phy-astr.gsu.edu/hbase/Nuclear/spinpol.html
