Weak interactions dominated by dispersion are important for van der Waals molecules, long-range forces, and some complex systems. A new class of functionals, called Double Hybrids (DH), have been developed more recently, to cure some of the difficulties encountered by more traditional DFT models. The purpose of this thesis is to better understand the non-covalent interactions with the non-empirical functionals. Firstly, an accuracy on Bond Separation Reaction (BSR) energies beyond the commonly-accepted threshold for chemical applications (errors ≤ 1.0 kcal/mol) can be obtained using a protocol combining a double-hybrid functional, such as PBE-QIDH or B2PLYP, with a D3-like empirical correction and a small split-valence basis set, DH-SVPD.
