High-resolution Fourier transform infrared spectra of the CH<sub>3</sub> <i>ν</i><sub>3</sub>and CH<sub>2</sub>D <i>ν</i><sub>4</sub> bands
Bibliographic record
Abstract
The spectrum of the ν3 band CH3 was observed in the 28003100 cm1 region with a Fourier transform infrared spectrometer. The 76 observed lines were analyzed together with the previous difference frequency data to determine the molecular constants including sextic centrifugal distortion constants and the A1 A2 splitting constant in the ground state. The ν4 band (out-of-plane vibrational mode) of CH2D was observed in the 550700 cm1 region by a discharge in a mixture of CH2DI and Ar. The molecular constants in both the ground and the ν4 states of this radical have been determined for the first time. PACS No.: 33.20Ea

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.
