In this work we present a low-order relativistic correction to the multipolar atom-light Hamiltonian for two bound particles corresponding to a simple model for Hydrogen like atoms and ions. From this result, we can systematically predict frequency shifts in atomic clocks based on trapped ions due to the mass defect. We also take into account non perfect traps, finding accordance with previous results and new corrections.
