Abstract
A detailed $^{2}\mathrm{H}$ nuclear magnetic resonance (NMR) study at $61.4\phantom{\rule{0.3em}{0ex}}\mathrm{MHz}$ of two chiral smectic $C$ phases of a smectogen 10B1M7, one ferroelectric $(\mathrm{Sm}{C}^{*})$ and the other antiferroelectric $(\mathrm{Sm}{C}_{A}^{*}$), is reported. Simulation of angular-dependent spectral patterns and/or signal intensities of the methyl deuterons are shown to provide information on the synclinic or anticlinic ordering, as well as the jump diffusion rates at different temperatures in the $\mathrm{Sm}{C}_{A}^{*}$ phase. The molecular self-diffusion constant is determined to be in the range of $0.2--1.2\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}14}\phantom{\rule{0.3em}{0ex}}{\mathrm{m}}^{2}∕\mathrm{s}$ over the temperature range of the $\mathrm{Sm}{C}_{A}^{*}$ phase. Molecular self-diffusion in the $\mathrm{Sm}{C}^{*}$ phase should be faster, but remains undetectable by the present approach. Furthermore, the phase biaxiality in these phases is found to be vanishingly small. The critical magnetic field for unwinding the helical structure of 10B1M7 is found to be relatively high.

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 itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
