GROUP 12 ELEMENTS AND THEIR SMALL CLUSTERS: ELECTRIC DIPOLE POLARIZABILITY OFZn,CdANDHg,Zn2DIMER AND HIGHERZnnMICROCLUSTERS AND NEUTRAL, CATIONIC AND ANIONIC ZINC OXIDE MOLECULES (ZnO,ZnO+ANDZnO-)

Abstract

This review is in general about group 12 elements and their small microclusters. In this part, after presenting an extensive literature survey of the electric dipole polarizability studies of the Zn , Cd and Hg atoms, we specifically target zinc-containing small clusters, beginning with the Zn2dimer, the Zn3trimer, higher Znnclusters and the neutral, cationic and anionic zinc oxide clusters: ZnO , ZnO+and ZnO-. We tabulated experimental and theoretical results for the spectroscopic constants (dissociation energy Deor D0, bond length re, fundamental frequency we, anharmonicity constant wexeand dipole moment μe) of the diatomic clusters and the first and second ionization potentials IP1and IP2and electron affinity EA of the species reviewed.
