Laser‐Blitzlichtphotolytische Untersuchungen zur Druckabhängigkeit der Reaktion ClO + NO2 + N2 → ClONO2 + N2

The kinetics of the reaction ClO + NO2 + N2 → ClONO2 + N2 was investigated at room temperature in the pressure range 28 < p < 824 mbar by ClO‐absorption measurements. As source for ClO radicals Cl2O was used. The reaction was initiated using monochromatic light pulses from a KrF*‐excimer laser at λ = 248.5 nm. A Xe‐high pressure lamp and a pulsed Mg‐hollow cathode lamp respectively were used as analytic light sources. The atomic emission of the hollow cathode source at λ = 285.2 nm coincides with the 8. vibrational state of the ClO absorption. The results are discussed and compared with data obtained in other experimental studies as well as in model calculations.
