Question

how is chemiluminescence produced

Answer 1

Chemiluminescence is the production of light from a chemical reaction. Two chemicals react to form an excited (high-energy) intermediate, which breaks down releasing some of its energy as photons of light to reach its ground state.

A + B -> AB* -> Products + Light

Example:

C₈H₇N₃O₂ + H₂O₂ 3 -APA [] 3 -APA + light

where C₈H₇N₃O₂ is luminol

H₂O₂ is hydrogen peroxide

3-APA is 3-aminophthalate

3-APA[] is the vibronic excited state fluorescing as it decays to a lower energy level.
