| Sažetak: | Title screen A method of definition of the focused localization of protons in the protonated crystals is offered. The method is based on the shooting of infrared (IR) ranges in polarized light and the analysis of integrated IR of a strip of absorption of valent fluctuations of X–H bonds depending on the rotation angle of the polarization plane [phi] relatively crystallographic axis of the crystal. The direction of the dipolar moment of X–H bonds answers a maximum of this dependence. The results of the researches of flat samples of crystals of LiNbO3 and LiTaO3 are given. The places of localization and orientation volume proton-containing centers are shown. The use of polarizing IR spectroscopy of materials with impurity proton-containing centers is a convenient method of definition of localization and orientation of protons and allows to study of interaction with other ions. The operability of the offered method is confirmed with the coincidence of theoretical and experimental results. Режим доступа: по договору с организацией-держателем ресурса |
