title: Formation of the Far Wings Contour of Spectral Lines Broadened by a Foreign Gas; Analysis of Exponential Decrease of Continuous Absorption Beyond the Band Head of the 4.3-micro Band of CO(2).
abstract: This paper presents a problem on the contour of a spectral line far off from its center. Integral representation of the absorption coefficient obtained in the paper by Anderson [Phys. Rev. 76, 647 (1949)] is used as a base. The problem is solved within adiabatic and binary collisions. Asymptotic methods are used for estimating the integrals over the collision parameters. Two formulas are obtained for the shape of line wings, one of which is of exponential form. On the basis of the theory developed, an interpretation is given for the radiation absorbed beyond the 4.3-micro band of CO(2) due to the strong line wings near the band center.
