UNIVERSAL SCALING OF THE RELAXATION NEAR A MODEL GLASS-TRANSITION

We report dielectric measurements of the orientationally disordered cr ystalline phase of cyclo-octanol over the frequency range 1.3 mHz-5.5 kHz. The data show that cyclo-octanol exhibits a slow relaxation that is indistinguishable in every respect from that exhibited by a superco oled liquid near its glass transition. In particular, the data obey a scaling relationship reported by Nagel and co-workers for a variety of structural glasses. These results show that cyclo-octanol is an ideal model system for studies of the glass transition, and suggest that th e scaling relationship is far more universal than expected.
