- In magnetic resonancespectroscopythe longitudinalrelaxationtime,
, is associated with spin-latticerelaxation, and the transverserelaxationtime, , with spin-spinrelaxation. The definitions are: and , where and are the components of magnetization parallel and perpendicular to the static field and the subscript e denotes the equilibrium value. - In a chemical reaction, the time,
, in which a concentration perturbation falls to of its initial value.
