Two Contributions to the International Symposium on the Physics and Chemistry of Ice. Held at Ottawa, Canada on 14-18 August 1972. The Dielectric Relaxation Spectra of Ice I(h) Single Crystals. Ice Chemistry: Is Ice I(h) a Proton Semiconductor.
Two reports are presented. (1) The ideal ice lattice without defects would show neither dipole orientation polarization nor conduction. In real ice crystals the author distinguished seven relaxation spectra in the frequency range between 100,000 and 0.008 Hz. The paper re-examines the experimental e...
