Abstract
1. On the basis of spectroscopic data the authors have refined the interpretation of the hydroxyl bands in the IR spectra of zeolites of the faujasite group with rare-earth cations. 2. In zeolites of type X, dehydrated in vacuum, the charges of the acid hydroxyl groups are compensated by the charges on the OH− and O2− anions. In zeolites of type Y, dehydrated in the same conditions, there are no O2− ions. 3. The authors suggest a probable mechanism for the influence of water coordinated by cations on the frequency of the acid hydroxyl groups.
