摘要
了解纯二氧化碳在较宽温度范围内的碰撞诱导吸收（CIA）对于富含二氧化碳大气的行星和系外行星的大气和气候研究是非常必要的。在这项工作中，利用傅立叶变换光谱仪测量了温度在 230 K 和 295 K 之间、压力高达 40 bar 的光谱，确定了 1150-4500 cm-1 光谱范围内的几个 CIA 波段，其中一些波段是首次测定。结果与文献报道的数值进行了比较，显示出良好的一致性。根据这项工作中获得的数据和文献中的数据，我们提出了与温度有关的波段形状和综合波段强度（IBI）的简单分析模型，从而可以计算出在较宽温度范围内所有已研究过的 CIA 转变。
Collision-induced absorptions by pure CO2 in the infrared: New measurements in the 1150–4500 cm−1 spectral range and empirical modeling for applications
Knowledge of collision-induced absorptions (CIA) by pure CO2 for wide temperature ranges is necessary for atmospheric and climate studies of planets and exoplanets with CO2-rich atmospheres. In this work, using spectra measured with a Fourier transform spectrometer for temperatures between 230 K and 295 K at pressures up to 40 bar, several CIA bands in the 1150–4500 cm−1 spectral range have been determined, in some cases for the first time. The results are compared with values reported in the literature, showing good agreements. From data obtained in this work and those in the literature, we propose simple analytical models for the temperature dependent band shape and integrated band intensity (IBI) which enable the calculation of all investigated CIA transitions in a wide temperature range.
期刊介绍：
Icarus is devoted to the publication of original contributions in the field of Solar System studies. Manuscripts reporting the results of new research - observational, experimental, or theoretical - concerning the astronomy, geology, meteorology, physics, chemistry, biology, and other scientific aspects of our Solar System or extrasolar systems are welcome. The journal generally does not publish papers devoted exclusively to the Sun, the Earth, celestial mechanics, meteoritics, or astrophysics. Icarus does not publish papers that provide "improved" versions of Bode''s law, or other numerical relations, without a sound physical basis. Icarus does not publish meeting announcements or general notices. Reviews, historical papers, and manuscripts describing spacecraft instrumentation may be considered, but only with prior approval of the editor. An entire issue of the journal is occasionally devoted to a single subject, usually arising from a conference on the same topic. The language of publication is English. American or British usage is accepted, but not a mixture of these.
