Abstract

The production of

O_{3}^{+}

by the ion‐molecule reaction

O_{2}^{+} {(a}^{4} Π_{u}) + O_{2} \to O_{3}^{+} + O

was investigated using a photoionization mass spectrometer. The photoionization efficiency for production of

O_{3}^{+}

by this reaction was measured from threshold at 742±2 Å (16.71±0.05 eV) to 650 Å (19.07 eV). The appearance potential of the

O_{3}^{+}

ion corresponds to reaction of

O_{2}^{+}

ions initially formed in the v′=5 vibrational level of the a ⁴Π_u state.
