The temperature dependence of collision-induced absorption by oxygen near 6 micronsCoefficients for oxygen absorption in the infrared induced by collisions with O2 and N2 are reported over the range 1400-1800/cm and 225-356 K. These coefficients are used to calculate the absorption for O2 in air as a function of temperature and wavenumber, and comparisons are made with previous determinations. In addition, structured absorption features superimposed on the broad collision-induced absorption band, which were observed at all temperatures studied, are interpreted in terms of the presence of (O2)2 and O2-N2 van der Waals molecules.
