The low frequency (102–105Hz) dielectric relaxation behavior of small dipolar molecules dispersed in supercooledo‐terphenyl has been studied below the glass transition temperature. Broad asymmetric loss curves are obtained for both rigid and nonrigid solute molecules. The relaxation times and Eyring activation enthalpies for molecular and intramolecular group reorientation processes are compared with the analogous values for the same solutes in a polystyrene matrix.
