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

Spectral induced polarization imaging to investigate an ice-rich mountain permafrost site in Switzerland
Ernesto Rey Cantor,Bertrall Ross +1 more
TL;DR: In this article , spectral induced polarization (SIP) measurements were collected at the Lapires talus slope, a long-term permafrost monitoring site located in the western Swiss Alps, to assess the potential of the frequency dependence (within the frequency range of 0.1-225 Hz) of the electrical polarization response of frozen rocks for an improved permafure characterization.

Comparison of the dielectric properties of normal and heavy water, absorbed on zeolites
TL;DR: In this article, the dielectric properties of NaA zeolite were studied at various degrees of adsorption of normal and heavy water, and it was shown that one of the relaxation processes observed in hydrated zeolites is associated with the relaxation of water molecules, whereas the other is probably of a different nature.

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.
