| chemiluminescence |
Chemiluminescence is the production of light photons by a chemical or electrochemical reaction. Chemiluminescence usually involves the oxidation of an organic compound such as luminol or acridinium esters by an oxidant such as hydrogen peroxide or hypochlorite. Chemiluminescent reactions occur in the presence of catalysts such as alkaline phosphatase, horseradish peroxidase, metal ions or metal complexes.

| chemisorption |
A process, related to adsorption, in which atoms or molecules of reacting substances are held to the surface atoms of a catalyst by electrostatic forces having about the same strength as chemical bonds. Chemisorption differs from adsorption chiefly in the strength of the bonding, which is much stronger in chemisorption.
