Abstract:Pseudo Jahn–Teller effects of triphenylene dianion were discussed by molecular orbital method. While the triplet ground state preferred a D3h geometry, singlet states were subject to symmetry lowering to have C2v geometries. The resultant geometries were rationalized to amplitude patterns of the degenerate frontier orbitals.
Keywords:Triphenylene   Dianion   Pseudo Jahn–  Teller effects   Spin states   Orbital phase
