The kinetics of the photolysis of CF3Br (Halon 1301) at various durations of irradiation of CF3Br−oxygen mixtures at a wavelength of 253.7 nm is studied. The spectra and absorbances of the reactants are obtained within the range of 200−900 nm using an M-40 spectrophotometer. Kinetic data are determined from a change in the absorption spectra at a wavelength of 416 nm, which corresponds to the maximum absorption of molecular bromine. A kinetic mechanism of CF3Br photolysis is proposed, and the quantum yield and the absorption cross section of CF3Br at this wavelength are determined. [ABSTRACT FROM AUTHOR] |
