What is Chemiluminescence?

Chemiluminescence is the the light that is produced via chemical reactions. Unlike light bulbs, in which a strip of filament is heated by electrical resistance to a flowing current until it glows, or even neon lamps, where electricity is run through a noble gas filled chamber, chemiluminescent light does not require electricity. In chemiluminescent reactions, one (or more) of the products of the reaction is produced at a high energy state, or more precisely, when the molecule is produced, one of its electrons is in a higher energy orbital than it would be in the ground state. The electron then falls to its ground state orbital, in the process releasing energy as electromagnetic radiation of a specific wavelength. If the wavelength is in the visible light spectrum, then the reaction produces light. This type of reaction is typified by the reaction that makes glowsticks glow.
