One advantage of introducing dispersion models in place of perturbation theory is a reduction in basisset demands, as ai D models are entirely independent of the basis set and MBD exhibits a mild basisset dependence. Extensive benchmarking of the XSAPT + MBD energy components has been reported recently, and Fig. summarizes how the choice of basis set impacts the accuracy of total interaction energies computed using SAPT(LRC-ω GDD PBE) + δHF + MBD.
