What Does EKT Stand For?

EKT stands for Extended Koopmans Theorem

EKT, or Extended Koopmans Theorem, is a theoretical framework in computational chemistry and quantum mechanics that builds upon the original Koopmans theorem. It provides a method for calculating the electronic structure of molecules by linking the energies of molecular orbitals to their ionization potentials and electron affinities. EKT extends the applicability of the original theorem by incorporating electron correlation effects, thereby offering improved accuracy in predicting the behavior of complex systems and enhancing our understanding of chemical reactivity and properties.
