説明
The positive ion–negative ion reactions of Kr^+ and Xe^+ with C_6F_5Br^- and C_6F_5CF_3^- have been spectroscopically studied in the He flowing afterglow. The branching ratios of recombination and neutralization reactions leading to RgX* excimers and excited Rg* atoms (Rg = Kr, Xe, X = Br, F), respectively, were determined to be 0.14:0.86 and 1.00:0.00 for the Kr^+/C_6F_5Br^- and Xe+/C_6F_5Br^- reactions and 0.00:1.00 for both the Kr^+/C_6F_5CF_3^- and Xe^+/C_6F_5CF_3^- reactions. It was concluded that electron affinities of target molecules and dissociation energies of C_6F_5X^- leading to X^- play a significant role in determining the branching ratio of ion–ion recombination and neutralization reactions.
