Polyvinyl butyral (PVB) is an amorphous polymer employed in many technological applications. In order to highlight the relationships between macroscopic properties and dynamics at a microscopic level, motions of the main-chain and of the propyl side-

Pyrochlore-type H3OSbTeO6 is a remarkable proton conductor exhibiting an outstanding electrical conductivity even at ambient temperature. It consists of a three-dimensional interconnected (Sb,Te)O6 framework, built from randomly distributed corner-sh

Deuteron spin-lattice relaxation and spectra were studied in partially and fully deuterated ( NH 4 ) 2 PdCl 6 in the temperature range 5–300 K. The relaxation rate maximum was observed at 45 K in ( ND 4 ) 2 PdCl 6 . Its value is reduced due to limi

We report on density functional theory computations combined with the results of measurements of the quadrupole coupling constants for $^{17}\textrm{O}$, hydroxyl deuterons, and adsorbed water deuterons in DX zeolite (n(Si)/n(Al) = 1). Calculations a

Deuteron spin–lattice relaxation is studied in 5% and 100% deuterated ammonium hexachlorostannate and perchlorate. The relaxation rate is observed to be independent of deuteration down to temperatures slightly lower than that of the maximum. At low
