    • 摘要: The electronic states of the ground state dissociation limit of SiO.SiS molecule are correctly determined based on group theory and atomic and molecular reaction statics. The structural optimization for the ground state (X1 ∑+)of SiO,SiS molecule has been calculated using density functional theory B3P LY and B3P86 method with the basis sets 6-311 + +G(3df,2pd) and D95(3df,2pd).
