Emission of light as a result of a chemical reaction Chemiluminescence (also chemoluminescence) is the emission of light (luminescence) as the result of a chemical reaction. There may also be limited emission of heat. Given reactants A and B, with an excited intermediate ◊, [ A ] + [ B ] ⟶ [ ◊ ] ⟶ [ products ] + light {\displaystyle {\ce {[A]{}+[B]->{}[\lozenge ]{}->{}[products]{}+light}}} For example, if [A] is luminol and [B] is hydrogen peroxide in the presence of a suitable catalyst we have: C 8 H 7 N 3 O 2 luminol + H 2 O 2 hydrogen peroxide ⟶ 3 − APA [ ◊ ] ⟶ 3 − APA + light {\displaystyle {\ce {{\underset {luminol}{C8H7N3O2}}+{\underset {hydrogen\ peroxide}{H2O2}}->3-APA[\lozenge ]->{3-APA}+light}}} where: 3-APA is 3-aminophthalate 3-APA[◊] is the vibronic excited state fluorescing as it decays to a lower energy level. https://en.wikipedia.org/wiki/Chemiluminescence
