Abstract:The ground and excited states of Sn 2 are calculated using the multireference configuration interaction method combined with Davidson correction (MRCI+Q). The influence of the spin−orbit coupling (SOC) effect on the electronic structure is also considered by the state interaction method of Breit−Pauli Hamiltonian. In the calculations, the potential energy curves and spectroscopic constants of 23 Λ-S states and 31 Ω states of Sn 2 are obtained. The prominent spectral features in the visible region, new constant… Show more
