Abstract
1 H and 2 H NMR spin-lattice relaxation times (T 1 ) have been studied as a function of temperature to obtain activation energies for the threefold reorientations of CH 3 groups (Ea = 22.83, 18.95, and 18.39 kJ mol 1 ) and NH 3 groups (Ea = 47.64, 45.31, and 28.74 kJ mol 1 ) in the β-phases of ethylammonium chloride, -bromide, and -iodide, respectively, for comparison with barriers determined from Raman torsional frequencies. T 1 , 2 H NMR lineshapes, and DSC studies have been used to clarify the existence of a β → α phase transition above room temperature in all three salts, and the absence of a transition at low temperature. 2 H NMR lineshape analysis indicates a rapid n-fold (probably fourfold) reorientation of the whole molecule in the α-phase. This motion occurs about an axis in the molecular CCN mirror plane in the bromide and iodide. In the chloride, the axis is in the plane perpendicular to the bisector of the DCD bond angle.Key words: ethylammonium halides, solid state 1 H and 2 H NMR, molecular dynamics, rotational barriers, phase behaviour.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
