Abstract:	The matrix isolation technique with Fourier transform infrared detection has been applied to determine the products of gaseous radical reactions. The gas phase reactions were carried out in a discharge flow system and about 1% of the gas mixture was deposited onto a low temperature target through a pinhole. A differential pumping scheme was employed to maintain the pressure of the cryosystem below 10-5 torr while that of flow system was kept at about 2 torr. Species including HO2 (from the H+O2 reaction), ClO2 (from the CI+O2 reaction) and CIO (from the Cl+O3 reaction) have been produced in the gas phase and were successfully trapped in inatrices and dctected with an FTIR spectrometer .In addition, both HCI and HOCL have been detected as the reaction products from the gaseous ClO+HO2 reaction. The production of HCI from the ClO+HO2 reaction may have a significant impact on catalytic ozone desiruction in the at atmosphere reactions were carried out in a discharge flow system and about 1% of the gas mixture was deposited onto a low temperature target through a pinhole. A differential pumping scheme was employed to maintain the pressure of the cryosystem below 10-5 torr while that of flow system was kept at about 2 torr. SPecies including HO2 (from the H+02 reaction), ClO2 (from the C1+O2 reaction) and CIO (from the Cl+O3 reaction) have been produced in the gas phase and were successfully trapped in inatrices and dctected with an FTIR spectrometer .In addition, both HCI and HOCL have been detected as the reaction products from the gaseous ClO+HO2 reactioit. The production of HCI from the ClO+H02 reaction may have a significant impact on catalytic ozone desiruction in theat atmosphere
