Branching ratio for $\text{O}+{\text{H}}_3^{+}$ forming ${\text{OH}}^{+}+{\text{H}}_2$ and ${\text{H}}_2{\text{O}}^{+}+\text{H}$

Pierre-Michel Hillenbrand, Nathalie de Ruette, Xavier Urbain +1

The gas-phase reaction of $\mathrm{O}+{\mathrm{H}}_3^{+}$ has two exothermic product channels, ${\mathrm{OH}}^{+}+{\mathrm{H}}_2$ and ${\mathrm{H}}_2{\mathrm{O}}^{+}+\mathrm{H}$. In the present…
