| Abstract: | Photochemical reactions of CH3Br, CH2Br2, CH3Br O2/O3 and CH2Br2 O2/O3 systems under the irradiation of 253.7nm is studied. The products are analysed by FTIR. and UV-Vis and reasonable mechanisms provided to explain the facts. Ozone photolysis in the presence of bro-momethane if further studied and relevant reaction model is raised to meet the result. |
