Chemical processes are studied in ozone formation by the photodissociation of oxygen molecule excited to the Schumann−Runge band at 193 nm with use of an ArF excimer laser. The experimental results at an O2 pressure of 100−500 Torr indicate that the ozone formation O + O2 + O2 → O3 + O2 is very rapid, that the predissociation O2 → O + O is a rate-determining process. The rate constant of the predissociation O2 → O + O is found to be 6.40 × 10-5 cm2 J-1 at 22.1 °C.
