摘要
本文首次报导Hel(21.22eV)紫外光电子能谱(UPS)用于ClONO_2的光化学反应研究.253.7nm紫外光光解ClONO_2的产物随光解时间的不同而异:光解15min后,产物为Cl_2,O_2和NO_2;光解25min和35min后,CINO的UPS谱峰清晰地显现在光解产物的UPS谱图中.从而提出了253.7nm 紫外光光解ClONO_2的反应机制.
The ultraviolet photolysis of C1ONO2 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 C1ONO2 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 C1ONO2 has been proposed.
