Journal ArticleDOI
Protonic conductivity at the superionic phase transitions in the M3H(XO4)2 crystal group
TL;DR: In this paper, a microscopic model for the description of the proton subsystem dynamics in superionic crystals with hydrogen bonds is developed, where the effect of the displacement of the nearest oxygens during hydrogen-bond formation is taken into account.

The superionic phase transition in hydrogen-bonded systems of the M3H(XO4)2 class: the effect of nearest-O(2) distortions on the proton dynamics
N. Pavlenko,I. V. Stasyuk +1 more
TL;DR: In this article, the behavior of protonic conductivity at the transition between the superionic state with a disordered system of hydrogen bonds and low-temperature states at which the different types of ordering in the H-bond network appear is investigated.

Raman studies of superionic phase transition in (NH4)4H2(SeO4)3
Maria Połomska,A. Pawłowski +1 more
TL;DR: In this paper, NIR FT Raman spectroscopy was used to investigate molecular groups dynamics in the vicinity of superionic phase transition in (NH4)4H2(SeO4)3.
Journal ArticleDOI
The roles of “ammonium” and “hydrogen-bond” protons in single crystals of the superionic conductor NH4HSeO4 by 1H NMR relaxation
TL;DR: In this paper, the variations with temperature of the line-shape, spin-lattice relaxation time, T1, and spin-spin relaxation time T2, of the 1H nuclei in NH4HSeO4 single crystals were investigated, and with these 1H NMR results, they were able to distinguish the crystals' "ammonium" and "hydrogen-bond" protons.
