Photoelectron spectra from ordered CO on Cu(111) exhibit anomalously small 4σ band dispersion compared to all other CO adsorption systems previously studied. The bonding 5σ band displays normal one-electron dispersion. It is shown that the energy dependence of the 4σ band expected for a single-particle system is transferred into k-dependent intensity variations of the quasiparticle excitation and the intense satellite line {~}2 eV lower in energy. The first moment of the spectral weight function over this energy range recovers the anticipated one-electron band dispersion.
