✦ Synopsis

Ab initio calculations have been performed on gallium phosphate clusters: Ga(OH);, P(OH):, (HO),GaOP(OH), and Ga,P,O,(OH)s.

The influences of the basis set and the level of theory on predicted configurations of the clusters are discussed. Calculated IR spectra have been analyzed and compared with experimental ones. The potential energy surface for the Ga-0 interaction has been used to derive force-field parameters. The latter were applied in the molecular dynamics simulation of the berlinite and low-cristobalite modifications of GaPO,.

CnN-cluster anions can be generated from laser ablation of appropriate samples. Mass spectrometry studies have found that the CnN-with odd n are much more stable than those with even n. Based on ab initio calculations for the electron detachment energies and fragmentation energies of CnN-anions, the
