The absorption by the oxygen A band near 13,100 cm(-1) (7620 A) has been investigated. Spectral curves with resolution between 0.6 cm(-1) and 1.2 cm(-1) have been obtained for several samples of O(2) and O(2) + N(2) 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) cm(2) 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(-l) 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 N(2) 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.
