HeI photoelectron spectroscopic (UPS) study of microwave-discharged species of the freon compounds——A HeI photoelectron spectrum of chlorine atoms

Freon compounds are the most important material to deplete the ozone layer in thestratosphere. Under atmospheric conditions, the species which are produced bychemical and photolysis reactions of freon can directly result in the destruction of theozone layer. But the reaction channel and mechanism between ozone and freon arenot clear now
