摘要: The experimental photoabsorption spectra of singly charged cationic mercury clusters Hg N + show a sharp change in behavior at cluster size N=6. Both relativistic density functional theory DFT and wave function based methods reveal that this corresponds to structural from linear three-dimensional isomers. simulated electronic excitation obtained time-dependent agree well with the results. Our quantum theoretical treatment confirms single electron-hole excitations small plasmonlike collective transitions for larger clusters.
