Carbon monoxide adsorption on the LTA-type zeolite Ca-A was studied by a combination of variable-temperature infrared spectroscopy and computational methods involving periodic density functional calculations and correlation between stretching frequency and bond length of adsorbed CO (omegaCO/rCO correlation). Based on agreement among calculated and experimental results, the main adsorption species identified were bridged Ca2+...CO...Ca2+ complexes formed on dual cation sites constituted by a pair of nearby Ca2+ cations.
