Matrix IR Spectrum and ab Initio SCF Calculations of Molecular SiS2

Article abstract of DOI:10.1021/ja00195a009

In solid argon molecular SiS2 is generated by a reaction of SiS with S atoms.The antisymmetric stretching vibration ν_as(SiS) is observed at 918 cm^-1.Bonding and structure (force constants from experimentally observed frequencies and results from ab initio SCF calculations) of SiS2 are compared with that of the similar molecules: CO, CS, CO2, COS, CS2, SiO, SiS, SiO2, and SiOS.
