This research aims to develop a Schrödinger perturbation expansion for examining exchange interactions in atomic and molecular systems.
Developed a perturbation expansion based on a complete, orthonormal set of symmetrized basis functions.
Defined unperturbed Hamiltonian and perturbation separately to maintain permutation-invariance.
Compared first and second-order results with prior work by Eisenschitz and London using non-orthonormal basis functions.
Demonstrated that the Schrödinger perturbation expansion effectively captures exchange interactions.
Second-order perturbation results align closely with those derived from Brillouin expansion.
