Formula and analytic methods have previously been explored for the evaluation of multicenter molecular integrals over Slater‐type orbitals by employing the Löwdin α‐function approach. These procedures are greatly simplified by numerical integrations. The programming of this numerical approach is straight‐forward and hence can serve as a check on future developments.
