The effect is considered of molecules leaving a cluster, within which their dielectric α-relaxation is described by a stretched exponential function . It is shown that an increase in their rate of leaving can lead to the relaxation of the system's polarization being described by a stretched exponential function with a stretching exponent larger than α and a relaxation time smaller than . The implications of this for time-temperature superposition and other properties of supercooled liquids are discussed.
