There were no significant changes in T 1ρ for 1H and 2H nuclei near T C, except for a change in the number of proton signals. The transition is driven by the number of resonance lines resulting from the crystal's ferroelastic properties. Near T m, the chemical shifts and T 1ρ values for 1H and 2H in the two materials changed abruptly, which implies variation of the structural geometry.
