WebThe principle of NMR usually involves three sequential steps: The alignment (polarization) of the magnetic nuclear spins in an applied, constant magnetic field B 0. The perturbation of this alignment of the nuclear spins by a weak oscillating magnetic field, usually referred to as a radio- frequency (RF) pulse.
