摘要

The photoabsorption spectra have been calculated for Sin and SinO (n≤5) clusters using time-dependent density-function theory.Our studies suggest that Sin-1O clusters are relatively stable than those of corresponding Sin clusters.Moreover, substantial differences are observed among the absorption spectra of different molecules in the energy region (0～8 e V).Comparing two different exchange-correlation potentials, local-density and generalized-gradient approximations, both calculated optical spectra present the same spectral feature.
