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-)

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 Zn 2 dimer, the Zn 3 trimer, higher Zn n clusters 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 D e or D 0 , bond length r e , fundamental frequency w e , anharmonicity constant w e x e and dipole moment μ e ) of the diatomic clusters and the first and second ionization potentials IP 1 and IP 2 and electron affinity EA of the species reviewed.
