Abstract: Chemical reaction between nitrogen oxides and dichloromethane, trich-loromethane, tetrach loromethane and 1,2-dichloroethane Lave been studied by Laser Magnetic Resoance through determination of NO/NO2 signals. In ultra-violet light and spark discharge respectively, dichloromethane,trichloromethane, tetrachloromethane and 1,2-dichloroethane can react with NO/NO2 rapidly. All of them are of great importance for understanding atmospheric chemical reaction and photochemical smog.
