Abstract
We discuss several aspects of the fluidized domain model advanced earlier to explain rotational and translational diffusion rates for fragile glass formers and, in particular, we point out weaknesses in the preceding Comment [Sillescu, Phys. Rev. E 53, 2992 (1996)]. Recent experimental results are cited to refine estimates of domain characteristics for orthoterphenyl at ${\mathit{T}}_{\mathit{g}}$ and to suggest that domain heterogeneity in space and time underlies stretched exponential relaxation behavior for rotational motion. \textcopyright{} 1996 The American Physical Society.
