The photochemical rupture of CF3OC(O)OONO2 at 254 nm leads to the formation of NO2 + CF3OC(O)OO, and NO3 + CF3OC(O)O radicals. The study carried out at 297, 273 and 253 K leads to a quantum yield φ{symbol}N O3 = 0.18 ± 0.03, and φ{symbol}N O2 + φ

Smog chamber/FTIR techniques were used to measure a 92 ± 7% yield of C8F17CH2CHO in the chlorine atom initiated oxidation of C8F17CH2CH2OH (8:2 FTOH) in 700 Torr of air. Relative rate techniques were used to measure k(Cl + C8F17CH2CHO) = (1.9 ± 0.4

The ultraviolet absorption spectrum of gas phase FC(O)OONO 2 has been measured over the wavelength range 200–320 nm for temperatures between 298 and 245 K. Absorption cross-sections were found to increase significantly with increasing temperature a

The UV absorption spectra of CF(3)CHO, C(2)F(5)CHO, C(3)F(7)CHO, C(4)F(9)CHO, CF(3)CH(2)CHO, and C(6)F(13)CH(2)CHO were recorded over the range 225-400 nm at 249-297 K. C(x)F(2)(x)(+1)CHO and C(x)F(2)(x)(+1)CH(2)CHO have broad absorption features cen

The ultraviolet absorption spectrum of gas phase CF3OONO2 has been measured over the wavelength range 200–340 nm at 233–300 K. Absorption cross-sections at wavelengths of 290–340 nm were found to increase significantly with increasing temperatu

FTIR smog chamber techniques have been used to show that reaction of CF 3 O 2 radicals with NO proceeds via two channels giving either CF 3 O + NO 2 (5a) or CF 3 ONO 2 (5b) as products. In 700 Torr of N 2 /O 2 diluent at 296 K the branching ratio for

CF 3 CF 2 C(O)F is a suitable source to generate the title radicals which can recombine to give back the precursor or lead to the formation of C 4 F 10 , CF 2 O and CO. We performed the photolysis of CF 3 CF 2 C(O)F pure and in the presence of c -C 6

The photolysis at 254 nm of perfluoroacetyl fluoride (CF3COF) in the gas phase yields C2F6, CF2O and CO as products. An excess of O2 added to the system leads to the formation of CF2O and CO2 as main products. If, instead of O2, c-C6H12 were added, t
