Abstract

The temperature dependences of the self-diffusion coefficient and the spin-lattice relaxation time have been studied by NMR measurements performed on a good glass former LICl-6H2O. The spin-lattice relaxation time can be separated into two relaxation processes, i.e., inter- and intramolecular processes. We have related these relaxation processes to the translational diffusion which corresponds to the primary or α-relaxation and to the local motions which are related to the β-relaxation in glass forming systems. The results throw some light to the evolution with temperature of these relaxation processes in the LiCl-6H2O system over the normal liquid, supercooled liquid and glass sates.
