The exact analytic first-order wavefunction of an H atom in the field of a proton obtained from the unsymmetrized perturbation theory as calculated in 1957 by Dalgamo and Lynn is used to calculate the exchange energy of Hz with the Holstein-Herring method.

The exchange energy between two atoms has been expressed in terms of a flux integral over a localized wavefunction by Holstein and Herring. By approximating this wavefunction to first order in polarization perturbation theory (Rayleigh-Schrijdinger theory) it is possible to calculate the exchange en

## Abstract The exchange polarization energy for the H~2~^+^ ion is expressed as an infinite sum of its angular components. At large internuclear distances __R__, a particular __l__โ€component, referred to as __induced__ __2__^__l__^โ€__pole exchange energy__, behaves asymptotically like For larger
