Experimental data were interpreted based on a very good agreement between theoretical and experimental results. The most intense band in the spectra centered at 2205 cm-1 was assigned to monocarbonyl complexes formed on Mg2+ cations located in the six-member ring separating two adjacent FER cages (P6 site); it is concluded that Mg2+ cations exchange preferably into this site. An unusually high site-specificity of CO observed for CO complexes formed in Mg-FER can be exploited in the investigation of preferable exchange sites of Mg2+ in zeolites and in the investigation of the localization of Al pairs in zeolites.
