A procedure is described for the precise nonrelativistic evaluation of the dipole polarizabilities of H₂⁺ and D₂⁺ that avoids any approximation based on the size of the electron mass relative to the nucleus mass. The procedure is constructed so that sum rules may be used to assess the accuracy of the calculation. The resulting polarizabilities are consistent with experiment within the error bars of the measurements and are far more precise than values obtained by other theoretical methods.
