SYNCHROTRON-BASED HIGH RESOLUTION FAR INFRARED SPECTROSCOPY OF BENZALDEHYDE
Bibliographic record
Abstract
The rotationally-resolved vibrational spectra of benzaldehyde have been recorded in the far infrared region at room temperature using the Bruker IFS125 Fourier Transform spectrometer at the Canadian Light Source with a resolution of 0.000959 \\wn. The lowest frequency vibrational bands collected correspond to the fundamental and hotbands of the -CHO torsion at 110 \\wn. The assignment and analysis of the dense spectral features in this region will be detailed. In addition, the newly obtained band origin of the -CHO torsional fundamental will be compared to \\emph{ab initio} results in relation to the discrepancy$\\footnote{L.D. Speakman, B.N. Papas, H.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
