Abstract
FO2. radicals are registered by IR LMR spectroscopy. The experimental ESR/I R LMR setup designed for the study of reactions involving FO2. radicals, as well as the methods for generating these radicals and measuring their abso lute concentrations, are described. The F + O-2 + M reaction is a reliable basis for the study of the reactions of FO2. radicals under jet conditions. The upper limit of the rate constant of the FO2. + FO2. reaction (k < 1.0 x 10(-14) cm(3)/s) and the probabilities of their heterogeneous decay on Ha loCarbon Wax gamma = (7 +/- 3.5) x 10(-5) are estimated. The consumption of the radicals in these reactions does not hamper the measurement of the FO2 . absolute concentrations.
