An analysis is presented of the optical emissions resulting from the sequential release of five gases (N2, Xe, CO, NO, and methylamine) from a remote canister as observed from a separate spacecraft by UV/visible array spectrometers and a pair of IR circular variable filter spectrometers. The releases occurred at 260 to 300 km altitude under conditions of no solar illumination. No emissions were detected during the N2 and Xe releases, but bright IR emissions in both fundamental and overtone vibrational bands observed for CO and No resulted from the highly energetic interaction of the released gases with the residual atmospheric gases. Molecular internal distributions and collisional excitation cross sections are derived. The collisional process creates highly rotationally and vibrationally excited CO and NO. Methylamine exhibited both IR and UV emission features attributable to OH(v), OH(A), and complex mid-IR emissions likely due to CH stretches and to NO and methylamine vibrational bands.
