摘要：

The temperature dependence of the characteristic length for the dynamic glass transition in orthoterphenyl is determined, for the first time, from combined results of depolarized dynamic light scattering, photon correlation spectroscopy, and viscosity experiments. The length is found to vary according to xi(a) is similar to (T - T(infinity))-v, where T(infinity) is the Vogel temperature, with an exponent v = 0.69 +/- 0.06 in the temperature region from T(g) up to T(g) + 80 K.
