    CCSDT and CCSD(T) Calculations on Model H-Bonded and Stacked Complexes

  • Original language description

    The CCSD(T) and CCSDT interaction energies were determined for model planar H-bonded complexes (formamide... form-formamide, formamidine... formamidine) and stacked complexes (ethylene... ethylene, formaldehyde... formaldehyde). Various basis sets from the 6-31G*(0.25) to aug-cc-pVDZ were used. Difference between CCSD(T) and CCSDT interaction energies were small and become negligible (bellow 0.1 kcal/mol) if the aug-cc-pVDZ (or aug-cc-pVDZ/cc-pVDZ) basis set was applied. This result strongly supports the use of the CCSD(T) method for determination of true stabilization energies of extended complexes.

    CCSDT a CCSD(T) výpočty modelových vodíkově vázaných a stacked komplexů

  • Czech description

    CCSDT a CCSD(T) interakční energie byly vypočteny pro modelové planární vodíkově vázané komplexy (formamide...formamide, formamidine...formamidine) a stackované komplexy (ethylene...ethylene, formaldehyde...formaldehyde). Byly použity různé báze 6-31G* až aug-cc-pVDZ. Rozdíly mezi interakčními energiemi CCSDT a CCSD(T) byly malé a staly se aznedbatelné při použití bází aug-cc-pVDZ (či aug-cc-pVDZ/c-pVDZ). Tento výsledek silně podporuje používání metody CCSD(T) pro výpočty stabilizačních energií rozsáhlejších komplexů.
