✦ Synopsis


Seven structures of the (H20) 7 are examined. Calculations were carried out with a Hartree-Fock wavefunction using the 6-311G *, and 6-311G * " basis sets. SCF force constants were calculated with both basis sets and the information used to generate thermodynamic data. The enthalpies, entropies, and free energies of the seven structures are presented and compared. Infrared and Raman spectra are also calculated and examined.

Three water hexamer structures found with a 3-2 1G basis set molecular orbital optimization method were explored with the HF//6-3 1 lG\* and HF/6-3 1 lG\*\* basis sets. Thermodynamic quantities and IR and Raman spectra were calculated. With the larger basis set the differences in electronic energy,

## Abstract We report on the structures of aluminum hydrides derived from a tetrahedral aluminum (Al~4~) cluster using __ab initio__ quantum chemical calculation. Our calculation of binding energies of the aluminum hydrides reveals that stability of these hydrides increases as more hydrogen atoms a
