摘要: Abstract UV absorption cross-sections of trichloroacetyl chloride (CF 3 C(O)Cl) have been measured using two different apparatuses with spectral resolutions 0.05 and 0.2 nm in the wavelength range 200–330 at temperatures ranging from 223 to 298 K. Photolysis studies CF C (O) C1 N 2 , air/C H 6 mixtures air performed 254 nm. Quantum yields for dissociation as a function pressure product quantum CO 296 K determined. The temperature-dependent new were used calculate photodissociation rate-constants C(O)C1 solar zenith angles altitude. Temperature effects rate constants are discussed.
