- Abstract
The kinetics of photodecomposition of Halons CFBr and CFBr was studied at different times of the irradiation of a mixture of these substances with oxygen at the wavelength λ = 253.7 nm. Kinetic data were obtained from changes in the absorption spectra in the region of Halon absorption and at a wavelength of 416 nm, which corresponds to the absorption maximum of molecular bromine. Kinetic schemes were proposed for the photodecomposition of CFBr and CFBr at λ = 253.7 nm, and the quantum yields of their photodecomposition at this wavelength were determined.
