Generalized Koopmans' theorem is applied to predict the vertical detachment energies and simulate the photoelectron spectra (PES). Intriguingly, the terminal S2-, polysulfide S2^2- and S3^2- ligands simultaneously emerge in the lowest-energy structure of MoS6. Molecular orbital analyses are performed to analyze the chemical bonding in MoS6^-/0 clusters and elucidate their structural and electronic properties.展开更多
