The 1 H nuclear magnetic resonance (NMR) spectra and the dipolar spin– lattice relaxation time T 1D for 1 H in the natural natrolite (Na 2 Al 2 Si 3 O 10 Á2H 2 O) have been measured in the temperature range of 190–390 K. From the temperature transformations of 1 H NMR spectra, it follows that at T [ 300 K, the diffusion of water molecules along the(More)
The shape of the free induction decay for the case in which the amplitude B1 (B1 = omega 1/gamma) of the RF pulse is comparable with local magnetic fields at sites of the nuclei is considered. It is shown that the shape of the FID G(t + tau) (where tau is the width of a RF pulse, t is the time after a RF pulse) depends on the shape of the FID G0(t)(More)
