LETTER TO THE EDITOR: The EPR evidence of local hydrogen bond distortion evoked by ? ions in ? crystals

An investigation of the influence of the proton subsystem on the EPR spectra of ions in is performed. The EPR superhyperfine structure from protons and their temperature dependences manifest the existence of asymmetrical configurations of protons at low temperatures. The preserving of the double-minimum character of proton potential on bonds in the near vicinity of ions is realized. It is suggested to be caused by redistribution of electron charges.
