Chemical reaction caused by light in which a bond is cleaved. (Calvert, 1990)

(Noun) The dissociation of a molecule caused by the absorption of a photon. 2. photolyze (Verb) The action of a molecule breaking apart after absorbing a photon. Ozone is photolyzed by ultraviolet light.

breaking of a chemical bond from the energy of a photon

a process whereby sunlight causes the chemical bonds in a molecule to break

(or Photolysed)—chemical decomposition by the action of radiant energy (as light).

Process by which a molecule reacts with light and is broken into smaller components.

sunlight causing the chemical bonds in a molecule to break

A chemical reaction involving sunlight in which molecules are split into their constituent atoms. Also known as photodissociation.

Chemical changes produced by use of radiant energy.

Chemical decomposition byway of radiation.

The process by which a chemical species undergoes a chemical change as the result of the absorption of a photon of light energy. See also photodecomposition, photochemical reaction, photooxidation.
