Abstract

Parameters of the SO₂–CO₂ line profile are important to study the carbon dioxide atmospheres of terrestrial planets (Venus and Mars) and exoplanets. The carbon-dioxide shift coefficients of sulfur dioxide lines in ν₁ + ν₃ band are calculated at room temperature; the rotational quantum numbers J varies from 0 to 100 and K_a varies from 0 to 20. Calculations were made using a semi-empirical method, which includes a correction factor with adjustable parameters depending on the rotational quantum numbers. The calculated shift coefficients are in good agreement with few published data.

SO2谱线co2位移系数的计算：ν1 + ν3波段

SO2-CO2谱线参数对于研究类地行星（金星和火星）和系外行星的二氧化碳大气具有重要意义。计算了室温下ν1 + ν3波段二氧化硫谱线的二氧化碳位移系数；转动量子数J在0 ~ 100之间变化，Ka在0 ~ 20之间变化。计算采用半经验方法，其中包括一个可调参数的校正因子，取决于旋转量子数。计算的位移系数与少数已发表的数据吻合较好。

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.
