Abstract
An investigation of the influence of the proton subsystem on the EPR s pectra of VO2+ ions in K3H(SO4)(2) is performed. The EPR superhyperfin e structure from protons and their temperature dependences manifest th e existence of asymmetrical configurations of protons at low temperatu res. The preserving of the double-minimum character of proton potentia l on bonds in the near vicinity of VO2+ ions is realized. It is sugges ted to be caused by redistribution of electron charges.
