Molecular orbital framework is of central importance in chemistry. Often used by chemists and physicists to gain insight into molecular properties, Hartree-Fock or Kohn-Sham orbitals are obtained from rather crude treatments and, strictly speaking, are not observables. Yet, quantum mechanics offers a route for connecting general many-electron wavefunctions with reduced quantities-density matrices and orbitals-which give rise to observable properties. Such mapping makes possible, in principle, reconstruction of these objects from
