Coupled Electron Pair Approximation

The Coupled Electron Pair Approximation is a computational method in quantum chemistry that belongs to the class of electron correlation techniques and specifically accounts for electron pair interactions by iteratively solving coupled equations for paired electron excitations while neglecting higher-order triple and quadruple excitation contributions.
