摘要：

Raman spectroscopy has been used as a direct structural probe to study sorbate-framework interactions for water sorption into the zeolite potassium-ZK5. Equilibrium adsorbate-induced deformations of intertetrahedral angles are quantitatively measured and analyzed in terms of a "structural isotherm" for each counterion site. All of the structural changes result from the first molecules sorbed. Kinetic studies of the structural deformation are used to determine a diffusion coefficient for the water molecules deforming the six-membered ring site of ∼ 10-12 cm2 s-1. © 1990 American Chemical Society.
