ExoMol line lists - II. The ro-vibrational spectrum of SiO

Accurate rotational-vibrational line lists are calculated for silicon monoxide. Line lists are presented for the main isotopologue, ²⁸Si¹⁶O, and for four monosubstituted isotopologues (²⁹Si¹⁶O, ³⁰Si¹⁶O, ²⁸Si¹⁸O and ²⁸Si¹⁷O), in their ground electronic states. These line lists are suitable for high temperatures (up to 9000 K), including those relevant to exoplanetary atmospheres and cool stars. A combination of empirical and ab initio methods is used: the potential energy curves are determined to high accuracy by fitting to extensive data from the analysis of both laboratory and sunspot spectra; a high-quality ab initio dipole moment curve is calculated at the large basis set, multireference configuration interaction level. A partition function plus full line lists of rotational-vibrational transitions are made available in an electronic form as Supplementary Information to this article and at www.exomol.com.
