Study of Ultraviolet Photolysis of C1ONO₂ （Chlorine Nitrate）by Means of HeI Photoelectron Spectroscopy （UPS）

The ultraviolet photolysis of CIONO₂ has been reported firstly by means of HeI （21. 22eV） photo-electron Spectroscopy （UPS）. With different photolysis time, the products of 253. 7 nm photolysis of CIONO₂ are different: after 15 min., the products are Cl₂,O₂, and NO₂, after 25min. and 35 min., the spectra of C1NO has been observed. So the mechanism of 253. 7 nm ultraviolet photolysis of CIONO₂ has been proposed.
