Salpeter equation in chemistry: relations with TD-DFT, applications ...
Third, TD-DFT has difficulties in accurately describing singlet?triplet transition energies, a problem that has been thoroughly investigated in the literature.
Time-Dependent Density-Functional Theory - Kieron BurkeWe review the theoretical background for obtaining both quantum defects and scattering phase shifts from time-dependent density functional theory.
