WebA photochemical reaction is a chemical reaction triggered when light energy is absorbed by a substance’s molecules. This response leads the molecules to experience a temporary excited state, thus altering their physical and chemical properties from the substance’s initial molecule. Photochemical Reaction. Webphotochemical reaction, a chemical reaction initiated by the absorption of energy in the form of light. The consequence of molecules’ absorbing light is the creation of transient excited states whose chemical and physical properties differ greatly from the original molecules. These new chemical species can fall apart, change to new structures, combine …
