The generation of paramagnetic palladium species in NaPd-Y and CaPd-Y zeolites adsorbed with water, hydrogen, and benzene has been studied by electron spin resonance and electron spin echo modulation spectroscopies. The probable locations of the Pd species are assigned on the basis of Pd-adsorbate interaction distances.
