Abstract
Photoionization methods have been used to study the reactions of the molecular ion in vinyl fluoride to yield the ionic products C_3H_3F_2^+, C_3H_4F^+, and C_3H_5^+. Quantitative measurements are reported of the effect of the vibrational state of the reactant ion on the product distribution and overall reaction cross section. Reaction cross sections for all three channels decrease with reactant internal energy. The effect on the reaction pathway producing C_3H_3F_2^+ is especially pronounced, with 0.18 eV of vibrational excitation being sufficient to reduce the reaction probability by 75%. Deactivation of vibrationally excited reactant ions competes with the reaction and is shown to be an efficient process.
