A b i n i t i o SCF calculations on molecular silicon dioxide

A b initio SCF calculations are performed on molecular silicon monoxide and dioxide. These computations show that the electronic ground state for molecular SiO2 is 1Σ+g and has a D∞h geometry, and that molecular SiO2 is bound with respect to SiO(1Σ+) and O(1D). Vibrational frequencies are computed in order to aid in the identification of this enigmatic species.
