alpha and beta relaxation time of glass forming solution LiCl-6H(2)O have been measured in three states; liquid, supercooled liquid, and glass. The beta process presents an original behavior which is analyzed. By using the Adam Gibbs and the Coupling Rearranging Region theory, we try to describe the alpha process. The predictive model of Perez based on these two theories give excellent results and a coherent interpretation of the observed phenomenon.
