OZONE GENERATION WITH NARROW-BAND UV-RADIATION

Ozone formation in oxygen at atmospheric pressure following the photodissociation of O2 molecules in the vacuum UV range is studied. A new VUV source based on incoherent xenon excimer radiation from a dielectric-barrier discharge provided narrow-band UV radiation at 172 nm with a half-width of 14 nm. The formation of ozone from the initial photodissociation fragments O(3P) and O(1D) is treated theoretically and compared to measurements.
