Low-Temperature Adsorption of N2, O2, and D2 on LiX, NaX, and NaLiX Zeolites Studied by FT-IR Spectroscopy

Abstract

FT-IR spectra of N2, O2, and D2 adsorbed on the dehydrated LiX, NaLiX, and NaX zeolites are studied at 77 K. The measured shifts of the bond-stretching frequencies and the integrated vibrational fundamental band intensities for admolecules are compared with the results of the recent high-level ab initio calculations. The effective electric fields in zeolite cavities are also reported.
