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,

Ab initio Hartree-Fock and Moller-Plesset second-order perturbation calculations have been performed on several structures of the water octamer which are expected to be in low-lying energy states. The ab initio results calculated with double zeta plus polarization basis sets predict that the global
