- Italian: termalizzazione
In physics, thermalisation (in American English thermalization) is the process of particles reaching thermal equilibrium through mutual interaction.
When a molecule absorbs energy, as in the technique of molecular fluorescence, the lifetime of the excited state is ~10-12 sec. Then it rapidly loses energy to the lowest level of the lowest excited state; this is called thermalization.
In general the natural tendency of a system towards a state of equipartition of energy or uniform temperature. This raises the system’s entropy.
Examples of thermalisation include:
