Abstract

Irradiation of pure oxygen at high pressure by a KrF excimer laser can produce ozone,^1,2 although its wavelength (248 nm) falls 0.12 eV short of the energy required to dissociate O₂ Experimental results indicate that ozone is produced through two processes: a slow process, which generates a small initial ozone concentration, and a fast process, which produces Ozone more efficiently once ozone is present. Thus, the process is autocatalytic. Freeman et al.³ suggested the following process for the initial ozone generation.
