Abstract
Abstract Raman and infrared spectra from 20 to 4000 cm −1 were recorded for crystalline deoxyadenosine samples at 300, 200, 100 and 10 K. The wavenumbers of most vibrational modes were found to increase as the temperature was lowered. No clear indication was found of any structural phase transitions in this temperature range. These data were compared with those from a previous Raman and infrared study of adenosine. New marker bands sensitive to the conformational identity of the ribose sugar ring are reported. Plausible assignments of all main spectral bands are suggested by comparison with assignments reported in the literature. Copyright © 2004 John Wiley & Sons, Ltd.

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
