The well-known problems associated with approximate KS-DFT in the description of dispersion interactions immediately raise the question whether sDFT can describe dispersiondominated molecular complexes correctly. To address this question, Schlüns et al. investigated the potential-energy curves obtained from sDFT with various combinations of NAXC and NAKE functionals. It turned out that the PW91 set of functionals, which are very popular in sDFT calculations, tend to overbind in many cases, while the combination of the BP86 NAXC functional with its "conjoint" counterpart LLP91 essentially reproduces the dispersion problems known in the context of KS-DFT for typical GGAs. This allows, in turn, to apply standard D3-type corrections to improve BP86/LLP91-sDFT calculations. By contrast, attempts to add empirical repulsive corrections to PW91/PW91k-sDFT calculations were less successful .
