Abstract

Holes being burnt into the dielectric relaxation ℰ(ω) are described as usual, but the effects are probed in terms of the time-resolved electric modulus M(t). In this way, it is possible to perform hole burning at frequencies more than five decades above those of the peak dielectric relaxation time τmax. Within the high frequency wing of glycerol, it is observed that the persistence time of the modifications are determined by the burn frequency and no longer by the structural relaxation time.
