A basis set optimized for double hybrid functionals in order to allow for an accurate evaluation of weak noncovalent interactions, thus, avoiding empirical dispersion corrections, whose use is particularly vexing for nonempirical functionals. Furthermore, large systems, such as the C60 dimer, are modelled at a reduced computational cost, due to their small size.
