Description
| - The structure of the phenol dimer and phenol...methanol complexes was determined by gradient optimisation using the Hartree-Fock (HF), MP2, DFT and RI-DFT-D methods. The following conclusions were made: 1) HF and DFT methods fail to predict cluster geometries; 2) MP2 procedure provides wrong geometries, only with small AO basis set, due to the compensation of errors, the geometries can be reliable; 3) the RI-DFT-D procedure covering the dispersion energy provides excellent geometries; 4) the stated results are valid for any molecular cluster, but the aromatic complexes are the most sensitive.

- Za použití různých metod teoretické chemie (HF, MP2, DFT, RI-DFT-D) byly gradientovou optimalizací určeny struktury dimer fenolu a komplexu fenol...metanol. Byly učiněny tyto závěry: 1) Metody HF a DFT selhávají při určení struktury molekulových klastrů; 2) MP2 metoda poskytuje špatné geometrie. Pouze při použití malé báze AO jsou díky kompenzaci chyb geometrie věrohodné; 3) metoda RI-DFT-D zahrnující disperzní energii poskytuje excelentní geometrie; 4) tyto závěry jsou platné pro všechny molekulové klastry, ale u aromatických komplexů se projeví více.
