A theory of electronic resonances based on spin-coupled wavefunctions is presented. The formulation is state selective and yields the best single-configurational minimax wavefunctions for resonance closed channels. The theory is demonstrated by calculations of positions, shifts and widths of resonances of a test system s-wave helium.
