Abstract

Oxygen atoms in the excited O(1D) state are a most important species in atmospheric chemistry. They can react rapidly with H2O to produce OH radicals. Strong evidence is given for the fact that O(1D) is produced with a quantum efficiency of one in the uv photolysis of ozone at wavelengths shorter than 300 nm. Reactions of O(1D) can therefore be studied by the photolysis of ozone as a convenient source. In this work reactions of both the excited O (1D) =O* and the ground state O(3P) = O oxygen atoms as well as the reaction of the metastable O2(1Δ) =O2* molecule are studied and rate constants determined by means of atomic resonance absorption spectroscopy. Since the ground state atomic oxygen concentration was monitored the question whether O2* is quenched physically or reacts chemically in collision with O3 could be decided.
