Photoelectron spectroscopy and density functional theory study of ConO− (n = 1-3)

- ConO− (n = 1-3) were investigated with photoelectron spectroscopy and calculations.
- The structures of ConO− (n = 1-3) were determined.
- The HOMOs of ConO− (n = 1-3) cluster anions are mainly localized on the Co atoms.
- The oxygen atom only had a minor influence on the electronic structures.
