Abstract

The absorption by the oxygen A band near 13,100 cm−1 (7620 Å) has been investigated. Spectral curves with resolution between 0.6 cm−1 and 1.2 cm−1 have been obtained for several samples of O2 and O2 + N2 with path lengths from 8 m to 1185 m and pressures up to 13.6 atm. The strength of the entire band is 4.09 ± 0.25 g−1 cm2 cm−1, and the relationship between the band strength and the strengths of the individual lines has been determined. Half-widths of self-broadened lines at 1 atm pressure vary from approximately 0.074 cm−1 at J = 2 to 0.043 cm−1 for J = 25. The lines are approximately 5% wider for air at the same pressure since broadening by N2 is more efficient than self-broadening. The wings of the lines absorb less than Lorentz-shaped lines beyond approximately 10 cm−1 from the centers.
