In those early days, the simple but incomplete picture prevailed that the dispersion energy is only relevant for the intermolecular situation -that is, for van der Waals complexes and condensed phases. The modern notion -namely, that intramolecular dispersion effects are especially important in large systems and in standard thermochemical applications -emerged only over the last ten years. Nowadays, newly proposed and accurate DFAs account for dispersion, which is mandatory for quantitative calculations and often even to obtain qualitatively correct results.
