Abstract
Raman scattering measurements were performed on the ferroelastic compound Rb(4)LiH(3)(SO(4))(4) to determine the nature of the structural transition observed at T(c) = 134 K. A double-grating spectrometer was used to obtain the Raman active B modes of Rb(4)LiH(3)(SO(4))(4). Back-scattering measurements, as a function of temperature, reveal that the 31 cm(-1) mode shows softening consistent with that of an order parameter. As a result, our investigation indicates that the structural transition in Rb(4)LiH(3)(SO(4))(4) should be cataloged as a pseudo-proper ferroelastic transition rather than a proper ferroelastic one.

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
