Abstract

Signatures of the slow β-relaxation of D-sorbitol as observed by macroscopic dielectric relaxation and solvation dynamics over a wide range of temperatures are compared. The latter technique senses the local dielectric relaxation in the immediate vicinity of a chromophore, which is present only at very low concentrations. The conformity of locally sensitized and macroscopically averaged results for the glassy state indicates that the secondary relaxation is a spatially uniform feature. If the β-process were spatially confined it should not be detectable by solvation probes.
