| Abstract: | By applying magic angle spinning to proton magnetic resonance of zeolites, two different lines were separated. Comparison of the corresponding resonance shifts with values of OH groups of other adsorbents and of organic compounds in solution showed that the signals must be due to hydroxyl groups of different acidity. |
