    Benzene Dimer: High-Level Wave Function and Density Functional Theory Calculations

  • Original language description

    High-level OVOS (optimized virtual orbital space) CCSD(T) interaction energy calculations (up to the aug-cc-pVQZ basis set) and various extrapolations toward the complete basis set (CBS) limit are presented for the most important structures on the benzene dimer potential energy surface. The geometries of these structures were obtained via an all-coordinate gradient geometry optimization using the DFT-D/BLYP method, covering the empirical dispersion correction fitted exclusively for this system. The fitwas carried out against two estimated CCSD(T)/CBS potential energy curves corresponding to the distance variation between two benzene rings for the parallel-displaced (PD) and T-shaped (T) structures. The effect of the connected quadruple excitations onthe interaction energy was estimated using the CCSD(TQ(f)) method in a 6-31 G*(0.25) basis set, destabilizing the T and T-shaped tilted (TT) structures by approximate to 0.02 kcal/mol and the PD structure by approximate to 0.04 kcal/mol.
