    The preferred Cu+ sites and formation of mono-, di-, and tricarbonyl complexes in the Cu-FER were investigated at the periodic density functional theory level and by means of FTIR spectroscopy. The site-specificity of adsorption enthalpies of CO on Cu-FER and of vibrational frequencies of polycarbonyl complexes were investigated for various Cu+ sites in Cu-FER.

    Stabilita polykarbonylových komplexů (mono-, di- a tri-) v Cu-FER byla studována pomocí periodických DFT (density functional) výpočtů a s použitím FTIR spektroskopie. Adsorpční entalpie a vibrační CO frekvence pro různá aktivní centra v systému Cu-FER byly zkoumány s ohledem na možnost jejich rozlišení v IČ spektrech.
