Abstract
Carbon dioxide absorption broadened by argon is studied on the basis of the asymptotic line wing theory. The line shape parameters concerned with the classical potential, which governs the center-of-mass motion, and the quantum intermolecular interaction potential are found. The temperature dependence of the CO2–Ar absorption beyond the 4.3 μm band edge is explained through changes in the classical potential, which describes the temperature behavior of the second virial coefficient in the temperature region under study.
期刊介绍：
Atmospheric and Oceanic Optics is an international peer reviewed journal that presents experimental and theoretical articles relevant to a wide range of problems of atmospheric and oceanic optics, ecology, and climate. The journal coverage includes: scattering and transfer of optical waves, spectroscopy of atmospheric gases, turbulent and nonlinear optical phenomena, adaptive optics, remote (ground-based, airborne, and spaceborne) sensing of the atmosphere and the surface, methods for solving of inverse problems, new equipment for optical investigations, development of computer programs and databases for optical studies. Thematic issues are devoted to the studies of atmospheric ozone, adaptive, nonlinear, and coherent optics, regional climate and environmental monitoring, and other subjects.
