Abstract

Working out the gas charge: Only one structure type is known for bulk MgO. In contrast, quantum chemical calculations combined with infrared multiple photon dissociation experiments demonstrate that neutral and cationic gas-phase clusters of MgO display unusual structural diversity and flexibility (see picture).
