    Stabilisation energy of C6H6 ... C6X6 (X = F, Cl, Br, I, CN) complexes: complete basis set limit calculations at MP2 and CCSD(T) levels

  • Original language description

    Stabilisation energies of stacked structures of C6H6...C6X6 (X = F, Cl, Br, I, CN) complexes were determined at the CCSD(T) complete basis set limit level. They are considerably larger than those calculated previously. Pseudopotential based calculationsshow, that due to relativistic effects hexaiodobenzene is less stable than hexabromobenzene. The SAPT decomposition of interaction energy into its components shows, that dispersion is the main stabilizing contribution.

    Stabilizační energie komplexů C6H6...C6X6 (X = F, Cl, Br, I, CN): výpočty s úplnou bázovou limitou na úrovních MP2 a CCSD(T)

  • Czech description

    Metodami MP2 a CCSD(T) byly vypočteny limity stabilizační energie v úplné bázi pro komplexy C6H6...C6X6 (X = F, Cl, Br, I, CN). Ty jsou daleko větší, než dosud publikované vypočtené hodnoty. Výpočty s pseudopotenciály ukazují, že díky relativistickým efektům je stabilizační energie hexaiodobenzenu menší, než u hexabromobenzenu. Byla provedena též dekompozice interakční energie na jednotlivé složky metodou SAPT. Hlavním příspěvkem ke stabilizaci komplexů je podle SAPT výpočtu disperzní energie.
