Abstract
High-frequency electron paramagnetic resonance (EPR) studies of the antiferromagnetic $\mathrm{Mn}\text{\ensuremath{-}}[3\ifmmode\times\else\texttimes\fi{}3]$ molecular grid clearly reveal a breaking of the $\ensuremath{\Delta}S=0$ selection rule, providing direct evidence for the mixing of spin wave functions ($S$ mixing) induced by the comparable exchange and magnetoanisotropy energy scales within the grid. This finding highlights the potential utility of EPR for studies of exchange splittings in molecular nanomagnets, which is normally considered the sole domain of inelastic neutron scattering, thereby offering improved sensitivity and energy resolution.

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
