N2 - CO interacts with exchangeable cations M+ (gray spheres in the picture) of zeolites to form M+ ··· CO and M+ ·· OC species (C: black; O: white) which are in a temperature-dependent equilibrium. For Na-ZSM-5 (M+ = Na+) the difference in interaction energy amounts to 3.8 kJ mol-1, as determined by means of variable-temperature FT-IR spectroscopy.
