Nitric oxide is an important compound in atmospheric chemistry and, with the use of an ozone generator, it is possible to use the chemiluminescent reaction as a sensitive way of measuring NO.

They occur in several species of firefly and in many species of bacterium. Firefly Luciferases are extracted by differential centrifugation and purified by gel filtration. Luciferins are substrates of luciferases . Firefly luciferin emits at 562 nm on reaction with oxygen, catalysed by luciferase in the presence of adenosine triphosphate (ATP) and magnesium ions.

It elaborates on how excess energy is released in various ways, including as heat through vibrational relaxation, through photochemical reactions, or as a photon via electromagnetic radiation.

This behavior is known as chemiluminescence and is transduction of chemical energy into radiant energy. Chemiluminescence is possible only when the ΔH of the reaction is sufficiently large to allow for production of at least one of the products in an electronically excited state.
