摘要：
The disordered structure of absorbed water in a highly porous zeolite chabazite Ca-2[Al4Si8O24]center dot nH(2)O (2 <= n <= 12.8) is studied from motionally narrowed H-1 nuclear magnetic resonance spectra at room temperature. Concentration phase transitions were observed at n approximate to 8.3 and n approximate to 10.2. The transitions are accompanied by displacement of Ca2+ ions and variation of the Broensted acid centers at inner surface of zeolite pores.
