Low-Temperature Collisions of O<sup>–</sup> Anions with CH<sub>4</sub> and C<sub>2</sub>H<sub>2</sub>: Reaction Rate Coefficients and Product Branching Fractions
Using a temperature-variable cryogenic linear 22-pole radiofrequency ion trap instrument, the temperature dependency of the rate coefficient of the reaction of O<sup>-</sup> anions with CH<sub>4</sub> has been measured at temperatures between 50 and 300 K. The temperature dependency of the rate coefficient of the reaction of O<sup>-</sup> with C<sub>2</sub>H<sub>2</sub> has been measured at temperatures between 145 and 300 K. For both reactions, the branching fractions characterizing associative detachment and anion formation were also determined.
