 Title    Na Spin-Lattice Relaxation Measurements in Dehydrated Na-X Zeolite  
 Abstract    The spin-lattice relaxation time T\ of 23 Na-NMR in a dehydrated Na-X zeolite has been measured from 20 to 300 K. The recovery curve is not single-exponential at all measured temperatures and T\~ 1 increases with the square of temperature around room temperature. The results are analyzed by assuming non-equivalent sites and by applying the theory of the Raman process based on covalency.
