Abstract

Activation energies, ~0.8 eV, of charges relaxing linearly or rotationally increase in steps of ~10^-2 eV due to equal quantum decreases of self-energy of depolarising dipoles. Plots of logarithm of current against time display series of straight sections defining relaxation time constants. A quantum approach allows derivation of several parameters and physical constants so far unobtainable from relaxation data. Linear superposition appears to be no longer valid in the nonequilibrium states. Complex permittivity variations with frequency can be attributed to the quantum changes of the self-energy of dipoles
