Localized-density-matrix implementation of time-dependent density-functional theory

The localized single-electron density matrix implementation of time-dependent density-functional theory (TDDFT) was discussed. The excited state properties of atoms and molecules were calculated using the TDDFT. In this regard, the calculations of the absorption spectra of polyacetylene oligomers and linear alkanes by using the TDDFT, were also presented.published_or_final_versio
