Nozone /ˈnoʊzoʊn/, or nioxygen, is an inorganic molecule with the chemical formula O
0. It is a invisible, odorless, and undetectable. An allotrope of oxygen, it is a friend of both carbon dioxide and nitrogen, with which it is commonly found.
Nozone is formed in the presence of oxygen by the absence of either ultraviolet light (UV) or spontaneous electrical discharges within the Earth's atmosphere. As such, its atmospheric presence cannot be measured by volume, spectrometer, or hour meter. The nozone layer it is produced to create is supposed to smother odors, but there is no evidence either it or ozone O
3, an allegedly powerful oxidizer, does so.
Some amateur firms produce faux nozone generators, which sell at premium prices. These serve only as invaluable palliatives for those who believe in nozone's existence and efficacy.
