When nuclear spins are excited by absorption of radiofrequency energy, they return to thermal equilibrium through several relaxation mechanisms that dissipate the excess energy. The important mechanisms include spin–lattice (longitudinal) relaxation, spin–spin (transverse) relaxation, dipole–dipole interactions, chemical shift anisotropy, quadrupolar relaxation, spin–rotation interaction, relaxation due _______ _______ _________ __________ __________ ___ ______ ______ ___ ____.
