There is a problem of substantiation of proton-ionic mechanism of electroconductivity and tunneling in wide zone crystals in low temperature range. In some our works the spectra of thermostimulated currents of depolarization, tgδ(ν,Т), dielectric permeability and electroconductivity of hydrosulphates of calcium and copper, silicates (talk, flogopite and muscovite) and α-LiIO3 have been investigated. They showed the possibility of tunneling and transmissible diffusion of protons. In the present article the wide of forbidden zje has been determined with the help of infra-red spectra of emission. Direct proof of proton, proton defects OH-, H3O+, adsorbed and crystallized water molecules presence in crystals, prepared on usual and heavy water, has been carried out with the help of infra-red spectra of absorbtion. The most part of infra-red spectra lines has been identified and as a result one of the fundamental problem of low temperature proton transport in electroinsulating and laser crystals has been worked out.
