Abstract
Time-of-flight secondary ion mass spectrometry (TOF-SIMS) analyzes chemical information by measuring ions generated via bombardment of an energetic ion beam on the surface of a specimen. Negative hydrocarbon ion species of C2nH− are ubiquitous in TOF-SIMS for any hydrocarbon-containing materials, but their utilities are perhaps not fully explored. Using polyethylene, polypropylene, polyisoprene, and polystyrene, the author demonstrates that C2nH− species possess intrinsic relationships, which offers unique TOF-SIMS ability for quantitatively differentiating the chemical structures of the four polymers.

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
