| Abstract: | Absolute reaction rates for F + HX and F + DX (X = I, Br, Cl) have been obtained by monitoring the rise time of HF (DF) vibrational fluorescence following multiphoton dissociation of SF6 in mixtures of HX (DX) and argon. The cross sections for reaction are, in units of 10?16 cm2, 4.37, 5.26, and 1.16 for HI, HBr, and HCl, respectively. The isotope effects kHX/kDX, are 1.29 ± 0.14, 1.29 ± 0.18, and 1.38 ± 0.29, respectively. |
