Abstract
The infrared spectrum of the weakly bound complex CO-orthoD2, which accompanies the fundamental band of CO in the 4.7 μm region, has been recorded at high resolution using a long-path (≈200 m), low-temperature (≈47 K), absorption cell coupled either with a Fourier transform spectrometer or with a tunable infrared diode laser. A total of 275 transitions, constituting most (>85%) of the observed lines, have been rotationally assigned in terms of 83 discrete quantum states of the complex. The positions of most of these energy levels have been accurately determined (<0.001 cm−1) for both the vCO=0 and 1 vibrational states. The binding energy of the complex, relative to the zero-point level, was determined to be about 30 cm−1. Predicted microwave and millimeter wave frequencies are given for the pure rotational spectrum. The energy level pattern derived here, together with that determined previously for the analogous CO-paraH2 complex, provides direct and precise information for testing and refining the intermolecular potential energy surface of the carbon monoxide–hydrogen system.

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
