dc.description Synthetic spectra have been calculated incorporating three O<sub>2</sub> emission systems, A³Σ<sub>u</sub><sup>+</sup> → X³Σ<sub>g</sub><sup>−</sup>, A′³Δ<sub>u</sub> → a¹Δ<sub>g</sub>, and c¹Σ<sub>u</sub><sup>−</sup> → X³Σ<sub>g</sub><sup>−</sup>, and matched to the 3100‐ to 4500‐Å nightglow spectrum of Broadfoot and Kendall (1968). The synthesis necessitated the inclusion of the c¹Σ<sub>u</sub><sup>−</sup> → X³Σ<sub>g</sub><sup>−</sup> system, which has never been previously identified in the airglow, although it is a dominant system in the Venusian nightglow. The emissions from the extremely metastable A′³Δ<sub>u</sub> and c¹Σ<sub>u</sub><sup>−</sup> states account for half the radiation in the 3100‐ to 4500‐Å region, from which it may be deduced that the mesospheric concentrations of O<sub>2</sub>(A′³Δ<sub>u</sub>) and O<sub>2</sub>(c¹Σ<sub>u</sub><sup>−</sup>) are much higher than that of O<sub>2</sub>(A³Σ<sub>u</sub><sup>+</sup>). The vibrational distributions are quite unrelaxed for all three states.
