Kinetics of fluorine atom reactions using resonance absorption spectrometry in the far vacuum ultraviolet reactions F + HCl, CH₄, CHCl₃ CHCl₂F, and CHClF₂

Atomic resonance absorption spectrometry with a nonreversed fluorine resonance lamp (∼95 nm) has been used to study the kinetics of elementary reactions of ground state F 2 P J atoms in a discharge‐flow system. The following rate constants (in cm 3 /molec·sec) All rate constants are given with 1.5 σ. were determined at 298° K: equation image The reaction F 2 P J + HCl(1) was found to give J‐excited Cl 2 P 1/2 atoms with a product branching ratio [Cl 2 P 1/2 ]/[Cl 2 P 3/2 ] = 0.10.
