Atmospheric Chemistry of CFH2CH2CH2CFH2: Kinetics and Mechanism of Reactions With Cl Atoms and OH Radicals

International Journal of Chemical Kinetics, Volume 58, Issue 7, Page 396-406, July 2026.
ABSTRACT The atmospheric chemistry of 1,4‐difluorobutane (CFH2CH2CH2CFH2) was investigated through a kinetic and mechanistic study of the reaction with chlorine (Cl) atoms and hydroxyl (OH) radicals. Using Fourier transform infrared (FTIR) spectroscopy and relative rate methods, the rate constants (k) for the reactions were determined at 298 ± 2 K as k(
