Title: Laboratory Studies of Oxygen Continuun Absorption
Published: July 01, 2003
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.
