CBS extrapolation of Hartree–Fock energy: Pople and Dunning basis sets hand-to-hand on the endeavour

AJC Varandas - Physical Chemistry Chemical Physics, 2019 - pubs.rsc.org
The Hartree–Fock (HF) energy is shown to be extrapolatable from subminimal, minimal, and
extended basis sets. Unprecedentedly, it can be reliably extrapolated to the complete basis …
