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

Solar and Stellar Astrophysics 2013-09-27 v1 Chemical Physics

Abstract

Accurate rotation-vibration line lists are calculated for silicon monoxide. Line lists are presented for the main isotopologue, 28^{28}Si16^{16}O, and for four monosubsituted isotopologues (29^{29}Si16^{16}O, 30^{30}Si16^{16}O, 28^{28}Si18^{18}O and 28^{28}Si17^{17}O), 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 \textit{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 {\it ab initio} dipole moment curve is calculated at the large basis set, multi-reference configuration interaction level. A partition function plus full line lists of rotation-vibration transitions are made available in an electronic form as supplementary data to this article and at \url{www.exomol.com}.
