摘要：
The EPR spectra of VO2+ complexes in Cs5H3(SO4)(4) . H2O have been investigated with the aim to study of SO42- ions and H2O molecules motions in the range (80-420) K. Results of EPR analyses presented, reveal gradual water molecules "freezing" down to T-g = 260 K and an additional SO42- unit freezing correlated to H2O. It is shown that correlated interaction between SO42- ions and water molecules leads to glassy-like freezing below T-g.
