Abstract
Raman spectra of nine anomerically stable monosaccharides have been obtained in aqueous solution in the 700-1700 cm(-1) spectral range. Good-quality spectra are obtained of solutions with concentrations as low as 10 mM and volumes as small as 15 microL. Interestingly, the Raman spectra appear to be exquisitely sensitive to the configuration of the carbon centers; unique spectra are obtained of all nine monosaccharides. The unique Raman spectral fingerprint observed for each monosaccharide, and for each anomer of each monosaccharide, suggests that Raman spectroscopy may be a useful technique for the identification and characterization of biologically relevant oligosaccharides. To test this idea, Raman spectra of three unknown disaccharides were obtained in a single-blind study. Identification of the individual monosaccharide components and their anomeric configuration was completely successful. All of these results suggest that development of Raman spectroscopy as a fast, sensitive discovery tool in glycobiology and carbohydrate chemistry is straightforward.

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
