Complex dielectric constants have been measured for ice from the melting point to −65°C, and for solid D2O to −35°C, by a combination of bridge and transient methods. For both, the dispersion is described by the simple Debye formula, and the relaxation times τ by the simple rate expression τ = A exp(B/RT). For ice, A = 5.3×10−16 sec, B = 13.2 kcal/mole; and for solid D2O, A = 7.7×10−16 sec, B = 13.4 kcal/mole. The equilibrium dielectric constant for ice is 91.5 at 0°C and increases at lower temperatures; the values for solid D2O are only slightly smaller. Measures taken to minimize errors from voids in the sample and direct current conductance are discussed.read more

TL;DR: Using time-resolved nonlinear dielectric relaxation measurements at fields as high as 450 kV/cm, the nonthermal effects of energy absorption are studied for simple and associating polar liquids in their supercooled state, explaining the incompatibility of heterogeneous dynamics with common physical aging observations.

Neutralization of Isolated Ion Pair in Polar Media. I. Theory for the Yield of Solvated Electrons
TL;DR: In this article, the authors describe the motion of an isolated ion pair in a polar medium with a time-dependent dielectric constant, where the time dependence is taken as appropriate to constant charge rather than to constant external field.

A Wide Range Capacitance‐Conductance Bridge
Robert H. Cole,Paul M. Gross +1 more
TL;DR: In this paper, the authors describe a bridge for reasonably accurate measurement by direct balance of capacitance and conductance in the frequency range 50 c/sec. to 5 cm/sec., and over most of this range is essentially direct reading in the two admission components with negligible unbalance from lead effects or guard circuits of the unknown.
