Sodium Y zeolites partially exchanged with Co 2+ have been studied by 129-XeNMR spectroscopy. Large chemical shifts due to paramagnetic effects of Co 2+ ions are observed when the water concentration is less than 6 H 2 O/Co 2+ . The 0 term (σ value for zero xenon concentration) derived from a second-order polynomial expansion is characteristic of ...
