Abstract

The frequency dependence of the proton longitudinal relaxation time in concentrated sugar in water solutions and glasses is compared with various theoretical models and used to derive correlation times characterizing the dynamic state of the water and sugar. It is shown that the water retains a high degree of molecular mobility even in the 'sugar glass', while the spectral density of the 3-dimensional glass lattice shows no evidence for a distribution of correlation times.
