ozone
n 1: a colorless gas (O3) soluble in alkalis and cold water; a
strong oxidizing agent; can be produced by electric
discharge in oxygen or by the action of ultraviolet
radiation on oxygen in the stratosphere (where it acts as a
screen for ultraviolet radiation)

The Collaborative International Dictionary of English v.0.48 (gcide)

ozone \o"zone\ ([=o]"z[=o]n or [-o]*z[=o]n"), n. [Gr. 'o`zwn
smelling, p. pr. of 'o`zein to smell. See {Odor}.] (Chem.)
A colorless gaseous substance ({O3}) obtained (as by the
silent discharge of electricity in oxygen) as an allotropic
form of oxygen, containing three atoms in the molecule. It is
a strong oxidizer, and probably exists in the air, though by
the ordinary tests it is liable to be confused with certain
other substances, as hydrogen dioxide, or certain oxides of
nitrogen. It derives its name from its peculiar odor, which
resembles that of weak chlorine.
[1913 Webster]
