The present study examines the effects of atmospheric production of NOX directly from the O2 and N2 principals via the reaction of O2(B3Σ) with N2 and a second process provisionally theorized as absorption of a photon with 190 ≤ λ ≤ 204 nm by O2•N2 collision complex. The NOX production from O2(B3Σ) is ~12% of the production from the classical O(1D) + N2O reaction in the region of their maxima in altitude. The diurnally averaged vmr (volume mixing ratios) of both NOX and NOY are enhanced similarly by 10 to 15% at the most. The NOX/NOY ratio is therefore unaffected. The production of NOX from O2(B 3Σ) compensates for the decrease in the classical production due to the recently discovered faster quenching of O(1D) by N2. In the O2-poor ancient atmosphere, when the solar UV in the Schumann-Runge bands penetrated much deeper into the denser lower atmosphere, the contribution of the NOX production from O2(B3Σ) may have been more pronounced than in the O2-rich present atmosphere. Below 22 km, NOX production from the second process far exceeds the classical production. Such a production would almost certainly lead to NOX and NOY vmr exceeding their observed values and would call for an extensive rethinking of the atmospheric NOX budget. Because these implications of the two new NOX sources are quite serious, attention has been drawn to many, equally serious, open issues at the levels of both laboratory experiments and basic quantal processes that require further studies.
