Under the no‐photon approximation, an effective quantum electrodynamics (QED) Hamiltonian can be constructed based solely on charge conjugation symmetry. It serves as the basis not only for the emerging field of “molecular QED” but also for various approximate Hamiltonians, including the standard no‐pair ones. The whole spectrum of relativistic Hamiltonians is hence completed. © 2013 Wiley Periodicals, Inc.
