论文摘要
二氧化硅(SIO $ _2 $)预计将发生在热岩石超级地球外行星的大气中,但缺乏光谱数据会妨碍其可能的检测。在这里,我们介绍了SIO $ _2 $的第一个全面的分子线列表。名为Oyt3的行列表覆盖了Wavenumber范围0 \, - \,6000〜cm $^{ - 1} $(波长$λ> 1.67 $〜$μ$ m),适合最多$ $ t = 3000 $ 〜k。使用强大的第一原理方法计算了近330亿个涉及569万旋转振动状态,旋转激发最高$ j = 255 $的过渡。 OYT3行列表可从http://www.exomol.com的Exomol数据库获得。
Silicon dioxide (SiO$_2$) is expected to occur in the atmospheres of hot rocky super-Earth exoplanets but a lack of spectroscopic data is hampering its possible detection. Here, we present the first, comprehensive molecular line list for SiO$_2$. The line list, named OYT3, covers the wavenumber range 0\,--\,6000~cm$^{-1}$ (wavelengths $λ> 1.67$~$μ$m) and is suitable for temperatures up to $T=3000$~K. Almost 33 billion transitions involving 5.69 million rotation-vibration states with rotational excitation up to $J=255$ have been computed using robust first-principles methodologies. The OYT3 line list is available from the ExoMol database at http://www.exomol.com.
