Abstract

Calculations will be presented of the vibrational distribution of O ₂ ⁺ in the terrestrial thermosphere for conditions of both low and high solar activity. At 100km, quenching precludes the survival of vibrationally excited O ₂ ⁺ . At 300km, about 50% of O ₂ ⁺ are in vibrational levels v≥1. The vibrational distribution is sensitive to the assumed values for the rate coefficient for quenching by atomic oxygen and for the vibrational distribution produced in the reaction

O ⁺ + O ₂ → O + O ₂ ⁺ (v≤7).

At high altitudes fluorescent scattering of radiation in the second negative system of 0 ₂ ⁺ is an important source of vibrationally excited 0 ₂ ⁺ . The effects of vibrational excitation of 0 ₂ ⁺ on the chemistry and airglow will be discussed.
