Relaxation

Relaxation stands quite generally for a release of tension, a return to equilibrium.

In the sciences, the term is used in the following ways: Relaxation (physics), and more in particular: Relaxation (NMR), processes by which nuclear magnetization returns to the equilibrium distribution Dielectric relaxation, the delay in the dielectric constant of a material Vibrational energy relaxation, the process by which molecules in high energy quantum states return to the Maxwell-Boltzmann distribution Chemical relaxation methods, related to temperature jump Relaxation oscillator, a type of electronic oscillator
