Title | Na Nuclear Spin-Lattice Relaxation in Dehydrated Zeolite NaY ![]() | ||
Abstract | The spin-lattice relaxation time T\ of 2, Na-NMR in dehydrated zeolite NaY has been measured from 26 to 300 K. The magnetization recovery curve is not single-exponential at all measured temperatures and 1 increases in proportion to the square of temperature above 200 K. The result is analyzed with a theory of the Raman process based on covalency. The value of T\ is compared with that of NaX in which the concentration of Na is about 2 times larger than in NaY. | ||
