Abstract
The ND3 deuteron spin−lattice relaxation time has been studied near the ferroelectric phase transition in single crystal triglycine sulfate. The results confirm proton−discorder motion in the hydrogen bond between glycine II and glycine III ions but they cast doubt upon the hypothesis concerning critical flipping of the glycinium I ion. Evidence is presented indicating faster hindered rotation of the glycinium I ND3 group compared to that of such groups at the other glycine ions.Keywords
