Abstract
Laboratory studies of the mid and near infrared collision-induced absorption bands of O2 are reviewed, with an emphasis on the 6.4 μm and 1.27 μm bands and on Ar, O2, N2, and CO2 collision partners. These absorption bands are important in the radiative balance of the atmo- sphere and contribute to the background absorption in remote-sensing radiometers. Also discussed is the ripple structure observed on the 6.4 μm band, which is absent from the 1.27 μm 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.
