1. In magnetic resonance spectroscopy the longitudinal relaxation time, T₁, is associated with spin-lattice relaxation, and the transverse relaxation time, T₂, with spin-spin relaxation. The definitions are:

and

where M_z and M_x are the components of magnetization parallel and perpendicular to the static field B and the subscript e denotes the equilibrium value.

2. In a chemical reaction, the time, τ, in which a concentration perturbation falls to 1/e of its initial value.
