| contents | Radiative corrections to electronic structure are characterized by perturbative expansions in $α$ and $Zα$, where $α$ is the fine-structure constant and $Z$ is the nuclear charge. A formulation of the leading-order $α(Zα)$ Uehling contribution to the renormalized vacuum polarization is reported in a form that is convenient for implementation in computational studies of the relativistic electronic structures of molecules. Benchmark calculations based on these methods are reported that include the leading-order vacuum polarization effects within relativistic mean-field methods for the E119$^+$ ion and the closed-shell diatomic species E119F. |
