Abstract
The infrared spectrum of the weakly bound complex CO–N2 has been studied using a pulsed supersonic slit-jet and a rapid-scan tunable diode laser. A mirror system giving 182 passes of the laser through the jet helped to give improved spectra with lower effective rotational temperatures (≈0.5 to 4 K) and less interference by CO dimer transitions. In the case of the CO-paraN2 spin modification, for which only one subband was previously known, over 10 linked subbands were assigned in terms of three ground (vCO=0) state stacks of levels (with K=0 and 1), and 7 excited state (vCO=1) stacks (with K=0, 1, and 2). In the case of the more abundant form, CO-orthoN2, an excited bending state was observed for the first time. The infrared analysis relied on precise ground state energy level differences obtained from microwave data.

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
