Аннотация

The dynamic structure of hydrogen sublattice in lawsonite, CaAl2[Si2O7](OH)2×H2O is studied by the solid-state proton magnetic resonance (1H NMR) spectroscopy of single crystal at room temperature. It is shown that both encapsulated water molecules, and hydroxyl OH-groups undergoes the rocking librations of the amplitudes of ~20° for H2O, and ~40° for hydroxyls.
