## Abstract The optimum projection technique is the determination of the best function in the space spanned by a set off __f__(N, S) linearly independent antisymmetric space‐spin eigenfunctions of S^2^ obtainable from a spatial function made of a product of __N__‐independent orbitals. This is formu

## Abstract The extended Hartree–Fock equations of the spin‐projected scheme are derived in a form suitable for the construction of a surely convergent method of solution using successive optimization of the individual orbitals. The derivation is based on a specific form of the generalized Brilloui
