Simple expressions are derived for all multipole, nonadiabatic, and finite-nuclear-mass corrections to the long-range effective potential due to two--Coulomb-photon exchange at threshold energy and also first order in energy correction for the scattering between a spinless point charged particle and a spinless Coulombic complex and between two spinless Coulombic complexes. All these corrections are treated on equal footing and the results are expressed, respectively, in terms of single-center and London-analog two-center atomic multipole spectral sums. An isomorphism between the point-particle--complex interaction and the complex-complex interaction is derived. All Hughes-Eckert--type mass-polarization terms are avoided by suitable choice of Jacobi coordinates.
