Abstract
In the present study we have observed rapid quenching of O2(a1&Dgr;) in O(3P)/O2/O3 mixtures. Oxygen atoms and singlet oxygen molecules were produced by the 248 nm laser photolysis of ozone. The kinetics of O2(a1&Dgr;) quenching were followed by observing the 1268 nm fluorescence of the O2 a1&Dgr;-X3&Sgr; transition. The temporal profiles of oxygen atoms O(3P) were monitored by means of the O+NO chemiluminescent reaction. The mechanisms of fast O2(a1&Dgr;) quenching in the presence of O atoms are discussed.
