Abstract
Abstract The use of Raman spectroscopy for the study of the molecular order in triglycerides is explored, with emphasis placed on three key spectroscopic fingerprints: (i) the CH stretching region at 3000–2700 cm −1 , (ii) the ester carbonyl (CO) stretching region at 1780–1700 cm −1 , and the CC stretching region at ∼1200–1100 cm −1 . Triglyceride polymorph and phase‐dependent changes related to the aliphatic chain and glycerol backbone conformation and packing, as well as changes in local environment, are ascertained on the basis of shifts in these bands. In particular, the ester carbonyl stretching region demonstrates clear differences between triglycerides polymorphs, as changes are seen in the number, stretching frequency, and size of the modes present. Besides, phase transition enthalpies are extracted from the Raman spectra of triglycerides studied. This chapter demonstrates that Raman spectroscopy is a viable tool for the characterization of triglycerides.

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
