Abstrakt: Earlier experiments based on comparing viscometer measurements of the viscosity of glycerol with the viscosity inferred from dynamic light scattering of Brownian particles have suggested the existence of an increasing microscopic length scale upon lowering the temperature towards the glass transition. We have performed accurate experiments on glycerol using Brownian particles of different sizes. Our results do not support the earlier claims. [ABSTRACT FROM AUTHOR]
