Abstract

Laboratory studies of the mid and near infrared collision-induced absorption bands of O₂ are reviewed, with an emphasis on the 6.4 m and 1.27 m bands and on Ar, O₂, N₂, and CO₂ collision partners. These absorption bands are important in the radiative balance of the atmosphere and contribute to the background absorption in remote-sensing radiometers. Also discussed is the ripple structure observed on the 6.4 m band, which is absent from the 1.27 m band. This structure has been attributed to dimers or to line mixing involving the weakly allowed electric-quadrupole absorptions. Finally, the strong enhancement of the collision-induced absorption by CO₂ collisions is shown.
