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.

基于渐近线翼理论计算 4.3 μm 波段波翼中氩扩增二氧化碳的吸收系数

摘要--基于渐近线翼理论研究了氩气对二氧化碳的吸收拓宽。找到了与支配质量中心运动的经典势和量子分子间相互作用势有关的线形参数。经典势的变化解释了 4.3 μm 波段边缘以外 CO2-Ar 吸收的温度依赖性，经典势描述了所研究温度区域内第二维里系数的温度行为。

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.
