(physical chemistry)
The use of radiant energy to produce chemical changes.



the decomposition of molecules that occurs when the molecules absorb light. The decomposition products may be molecules with a smaller number of atoms, free radicals or atoms, or positive and negative ions. If the products are free radicals or atoms, the process is called photodissociation. If the products are positive and negative ions, the process is known as photoionization.

Thus, motile epipelic algae may benefit from UV radiation by adjusting their position within the sediments so as to avoid high UV irradiance, yet exploit periods of photolytically enhanced resource availability.
Polyurethane substrates such as adhesives, sealants, elastomers and fibers may require a multi-component stabilization approach in order to reduce the effects of both oxidative and photolytically induced degradation.
