Fourier transform infrared smog chamber techniques were used to study the kinetics and mechanisms of the reactions of Cl atoms and OH radicals with pentafluorophenol (C6F5OH) in 700 Torr total pres...

Smog chamber/Fourier transform infrared (FTIR) techniques were used to measure the kinetics of the reaction of n-CH2═CH(CH2)xCN (x = 0–4) with Cl atoms, OH radicals, and O3: k(CH2═CHCN + Cl) = (1.03 ± 0.13) × 10–10, k(CH2═CHCH2CN + Cl) = (2.02 ± 0.35) × 10–10, k(CH2═CH(CH2)2CN + Cl) = (2.75 ± 0.45) × 10–10, k(CH2═CHCN + OH) = (4.21 ± 0.95) × 10–12, k(CH2═CHCH2CN + OH) = (1.55 ± 0.34) × 10–11, k(CH2═CH(CH2)2CN + OH) = (2.98 ± 0.64) × 10–11, k(CH2═CH(CH2)3CN + OH) = (3.34 ± 0.64) × 10–11, k(CH2═CH(CH2)4CN + OH) = (3.61 ± 0.85) × 10–11, k(CH2═CHCN + O3) = (2.55 ± 0.28) × 10–20, k(CH2═CHCH2CN + O3) = (1.17 ± 0.24) × 10–18, k(CH2═CH(CH2)2CN + O3) = (3.35 ± 0.69) × 10–18, k(CH2═CH(CH2)3CN + O3) = (4.07 ± 0.82) × 10–18, and k(CH2═CH(CH2)4CN + O3) = (7.13 ± 1.49) × 10–18 cm3 molecule–1 s–1 at a total pressure of 700 Torr of air or N2 diluents at 296 ± 2 K. CH2ClC(O)CN, HC(O)CN, HC(O)Cl, HCN, NCC(O)OONO2, and ClC(O)OONO2 were identified as products from the Cl initiated oxidation of CH2═CHCN. The product spectra w...
