Cleavage of one or more covalent bonds in a molecular entity resulting from absorption of light, or a photochemical process in which such cleavage is an essential part. Note: Term often used incorrect [..]

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.

A chemical reaction in which a compound is broken down using light energy. Photosystem II uses water photolysis to replace the electrons emitted from its reaction centre.

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

The cleavage of one or more covalent bonds in a molecular entity resulting from absorption of light, or a photochemical process in which such cleavage is an essential part. For example: Cl2 2 Cl. The term is used incorrectly to describe irradiation of a sample, although in the combination flash photolysis this usage is accepted. IUPAC PHOTOCHEMICAL [..]

Illustrated Glossary of Organic Chemistry Photolysis: From photo (light) and lysis (breaking). A reaction in which the absorption of light results in the breaking of bond(s). More generally (but less [..]

Chemical bond cleavage reactions resulting from Absorption of radiant energy.

Chemical decomposition by the action of light and the lysis or solution of cells under the influence of light. (Dorland, 28th ed)

Chemical decomposition induced by light or other energy.

A chemical reaction in which chemical compounds are broken or separated caused by light.

The destruction of a molecule by electromagnetic radiation, which provides the energy required for a constituent atom to break the chemical bonds between it and the other atoms comprising the molecule [..]
