Abstract

Accurate measurements of collision-induced absorption by O2 and O2–N2 mixtures in the fundamental band near 6.4 µm have been made. A Fourier-transform spectrometer was used with a resolution of 0.5 cm-1. Absorption has been investigated in the 0–20-atm and 193–293 K pressure and temperature ranges, respectively. The current measurements confirm that the broad O2 continuum carries small features whose attribution is not yet clear. Available experimental data in the 190–360 K temperature range have been used to build a simple, low cost computer, empirical model that is well adapted for computation of atmospheric O2 absorption. Tests show that it is accurate, contrary to predictions of widely used atmospheric transmission codes.
