TLDR
In this article, 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.Abstract:
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

Interpretation of the Energy of Hydrogen Bonding; Permanent Multipole Contribution to the Energy of Ice as a Function of the Arrangement of Hydrogens
TL;DR: A comprehensive calculation of the permanent multipole lattice energy of ice I, performed as part of a study of the orientational energy of the ice and the nature of the hydrogen bond, has led to the following conclusions: (1) The energy for existing quantum-mechanical models can be approximated with simple point-charge models as discussed by the authors.

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.
