NMR method for determining kinetics of chemical exchange by perturbing the magnetization of nuclei in a particular site or sites and following the rate at which magnetic equilibrium is restored. The most common perturbations are @S05472@ and @I03146@, and the corresponding techniques are often called '@S05478@' and 'selective @I03146@-@R05206@'.
