Spectroscopy where the energy states of 14N nuclei placed in a static magnetic field are interrogated by inducing transitions between the states via radio frequency irradiation. Each experiment consists of a sequence of radio frequency pulses with delay periods between them. Anisotropic interactions between nuclei, which are usually averaged by Brownian motion in liquid samples, cause significant line broadening in solid-state NMR, but can be averaged to zero by spinning the sample very rapidly at the magic angle (54.74° with respect to the direction of the magnetic field).
