【Abstract】 The gaseous reaction of CH+NO 2 has been investigated experimentally. CH radical was generated by multiple photon photolysis of CHBr 3 at 248 nm. Vibrationally excited species of HCO (ν 3), CO( v ), CO 2 (ν 3), HNO (ν 1), OH( v ) were detected as emitters of CH+NO 2 reaction by time resolved Fourier transform spectroscope. Three exothermic reaction channels leading to HCO+NO, NH+CO 2, CO+HNO, are identified. The minor reaction leading to OH+NCO may also occur.更多还原
