Abstract:SiH has long been observed in the spectrum of our Sun and other cool stars. Computed line lists SiGHTLY for the main isotopologues of silicon monohydride, ^28^SiH, ^29^SiH, ^30^SiH and ^28^SiD are presented. These line lists consider rotation-vibration transitions within the ground X ^2^{Pi} electronic state as well as transitions to the low-lying A ^2^{Delta} and a ^4^{Sigma}^-^ states. Ab initio potential energy (PECs) and dipole moment curves (DMCs) along with spin-orbit and electronic-angular-momentum couplings between them are calculated using the MRCI level of theory with the MOLPRO package. The PEC for the ground X state is refined to available experimental data with a typical accuracy of around 0.01cm^-1^ or better. The ^28^SiH
