Abstract
It has been previously demonstrated1 that irradiation of pure oxygen at near atmospheric pressures by unfocused 248-nm excimer laser radiation can produce equilibrium ozone densities exceeding 1015 cm−3, although radiation at this wave-length falls 0.12 eV short of the energy required to dissociate O2. Ozone is generated at a very low density by an undefined mechanism. These molecules are then photodissociated to produce an oxygen atom plus a vibrationally excited O2 molecule (quantum yield = 0.1). A second photon dissociates the molecule so that three atoms (and henee three new O3 molecules) are generated from each ozone molecule which undergoes this sequence, and the process is autocatalytic.
