摘要: By the comparison of experimental results and computational data concerning interaction CO with one or two naked cations, evidence is provided that weak bands occurring in IR spectra basic zeolites, after low-temperature adsorption CO, at frequencies lower than gaseous molecule, are due to species O-bonded a single cation thermodynamic equilibrium usual, more stable C-bonded same cation. The absence O-bonding for other systems discussed, probable occurrence protonic zeolites.
