Reaction of CH with NO2 studied by time-resolved FTIR spectroscopy
The gaseous reaction of CH + NO2 has been investigated by using time-resolved FTIR spectroscopy. The CH radical was generated by the laser photolysis of CHBr3 at 248 nm. All of the reaction products, NO, CO, HNO (v(1)), CO2 (v(3)) and OH, in their vibrationally excited states were observed. The reaction leading to CO + HNO is identified as the most favorable channel. Producing HCO + NO is a minor reaction channel. A much less competitive channel leading to OH + CNO may also occur. The observed CO2 species may come from the secondary reaction HCO + NO2. The observation agrees with the recent theoretical prediction based on ab initio calculations.
