Density functional theory for a single excited state is presented using Kato's theorem and the concept of adiabatic connection. The degenerate case is also detailed. The optimized potential method is generalized. The generalized Krieger, Li, and Ž . Iafrate KLI approximation is derived.
For Hamiltonians which are invariant under a group of transformations, one can restrict the search for the energy eigenstates in spaces whose functions transform according to the irreducible representations of the group. However, the construction of a Slater determinant to represent the equivalent n
A spin-annihilation technique for a single determinant formed from Kohn-Sham orbitals is described for the calculation of excited state singlet energies. This procedure accurately calculates the 1 IB u ~ 1 lAg vertical transition for s-trans-l,3butadiene using the Becke-Lee-Yang Parr (BLYP) function
