Chemiluminescence is the process by which a compound emits light as a result of a chemical reaction. This reaction often involves the oxidation of a substance, resulting in the release of energy in the form of light. The term "chemiluminescence" was coined in the 19th century to describe this phenomenon, which is distinct from bioluminescence, the light emitted by living organisms.

In a chemiluminescent reaction, the energy released during the reaction is transferred to the excited state of a molecule, which subsequently releases this energy as light. This process occurs when a molecule reacts with another molecule to produce an excited species, such as an atom or a radical. The energy released as light is a result of a transition from the excited state to a lower energy state.

Chemiluminescence is commonly observed in various chemical reactions, including the oxidation of certain organic compounds. For example, the reaction between hydrogen peroxide and a suitable catalyst can produce intense light. Other examples include the oxidation of luminol, a chemical used in forensic science to detect bloodstains, and the reaction between certain organic compounds and azide radicals.

Chemiluminescence has practical applications in various fields, including analytical chemistry, biomedicine, and forensic science. It is also used in the development of assays, sensors, and other diagnostic tools. Researchers continue to study chemiluminescence to better understand the underlying chemical mechanisms and to explore new applications for this phenomenon.
