Abstract:

This report examines point defects in ice molecular defects vacancies and interstitials, protonic point defects ions and Bjerrum defects and electronic point defects solvated electrons and radicals. Experimental results and theoretical models of the defects atomic and electronic structures, energies and mobilities are reviewed. Special attention is given to the results of studies from the last two decades. Among the experimental techniques under consideration are nuclear magnetic resonance, X-rays topography, electron spin resonance, measurements of ice conductivity and dielectric permittivity, spectra of optical absorption and photoluminescence and measurements of diffusion coefficients of the oxygen and hydrogen isotopes in ice. Ab initio calculations, computer simulations, Jaccards theory and soliton models are used to discuss the defects structures and their properties.
