摘要
The geometries of hyperlithiated compounds OLin were optimized by means of HF, MP2 and DFT methods with 6-31G(*) basis set. The dissociation energies of those optimized stable geometries of OLi8, were calculated, the results are in good agreement with experimental values; and moreover, the dissociation energy of OLi6 is predicted. In addition, the fundamental vibrational frequencies were also predicted.
