Water dynamics in deuterated gypsum, CaSO⋅2DO, investigated by solid state deuterium NMR.

NMR relaxation theory and NMR lineshape calculations were used to characterize the rates of C symmetry jumps of deuterium nuclei in partly deuterated gypsum powder. The experimental data consisted of variable temperature deuterium NMR powder line shapes and deuterium T relaxation times. All of the Mathematica© notebooks used to simulate the spectra and match the experimental T values are included as supplementary material, and are suitable templates for similar calculations on other systems.
