The Shapes of Collision-Broadened CO2 Lines
Abstract
The shapes of the extreme wings of self-broadened CO2 lines have been investigated in three spectral regions near 7000, 3800, and 2400/cm. Absorption measurements have been made on the high wavenumber sides of band heads where much of the absorption by samples at a few atm is due to the extreme wings of strong lines whose centers occur below the band heads. Considerable new information has been obtained about the shapes of self-broadened CO2 lines as well as CO2 lines broadened by N2, O2, A, He, and H2. Beyond a few reciprocal cm from the line centers all the lines absorb considerably less than Lorentz- shaped lines having the same half-widths. The deviation from the Lorentz shape decreases with increasing wavenumber in going from one of the three spectral regions to the next.
