SiO

Energy levels, Einstein A coefficients and transition frequencies were obtained from Barton et al.(2013). Based on SiO–H calculation (v=0–5,J=0–39) from Palov et al. (2002, 2006) and original SiO–H₂ LAMDA data file (v=0,J=0–40), we construct comprehensive rovibrational collisional rate coefficient data set. SiO–He rovibrational rate coefficients are obtained by, 1) retrieving v=0 data from LAMDA database (reduced mass approach with a factorof 1.38), 2) scaling v=1–5 SiO–H data Palov et al. (2002, 2006) with reduced-potential method and 3) including high temperature data from Balanca & Dayou(2017). We also apply reduced-potential scaling method to SiO–He (v=0) and–H (v=1–5) data to determine SiO–H₂ rate coefficients.

Full dimensional close coupling (6DCC) and five-dimensional coupled-states (5DCS) methods are applied to calculate the SiO-H₂ state-to-state rovibrational rate coeffiicents.
