C4S4m-相对稳定性的从头算研究
Ab Initio Study of the Relative Stability of C4S4m-
【Abstract】 We have used an ab initio self-consistent field(SCF) molecular orbital approach toinvestigate the equilibrium geometry and relative stability of C4S4m- (m=0,1,2,3,4). We foundthat the geometry of anions studied from m=0 to m=4 changes from non-aromatic structure toaromatic structure and fmally anti-aromatic structure and that the relative stability decreases inthe order of: C4S4m- > C4S42- > C4S4 > C4S4 > C4S4.
