Abstract
The v 2, v 3 bands and v 1, 2v 2 Fermi diad of CO2 are observed in NaA and CaA zeolites at 306 and 193 K. The frequency shifts are compared with the shifts calculated in the harmonic oscillator approximation by Wilson's method. We consider only the electrostatic effect of the zeolite electric field. This calculation shows the perturbation on the force constants; this effect is not sufficient to account for the observed shifts.Keywords
