cze	Characterization of Cu+ sites in FER: Combined computational and experimental TPD study.	CO-TPD spektra získaná na sadě Cu+-FER zeolitů byla zkoumána kombinací experimentálních i teoretických technik. Na základě kvantově mechanických modelů byly ve struktuře FER zeolitu nalezeny tři typy Cu+ centre s adsorpčními energiemi -122, -76, a -59 kJ/mol. Analýzou TPD spekter byly nalezeny tři desorpční centra s energiemi -121, -86, a -62 kJ/mol. Studiem Co-TPD křivek an Cu+-FER zeolitech lze tedy získat informace o distribuci Cu+ iontů v jednotlivých centrech a také informace o distribuci Al v mřížce.
eng	Characterization of Cu+ sites in FER: Combined computational and experimental TPD study.	CO-TPD spectra of CO/Cu+/FER system were investigated and analyzed by a combination experimental and theoretical techniques. Three Cu+ sites characterized by adsorption energies -122, -76, and -59 kJ/mol were found using a combined quantum mechanical/interatomic potential function method. Three Cu+ sites with CO adsorption energies -121, -86, and -62 kJ/mol can be distinquished from TPD analysis. Site distribution na dinfromation about the framework aluminium distribution in FER is obtained.	FER Zeolites;Cu+ sites
