Abstract
The van der Waals complex NH3-CO has been studied in the infrared and millimetre wave regions, and analysed on the basis of the distinction between the ortho- and para- NH3-CO nuclear spin species. The spectrum and energy level pattern of ortho-NH3-CO are relatively simple, closely resembling those of the Ne-CO and Ar-CO complexes. The situation for para-NH3-CO is somewhat more complicated, with observed states having K values which differ by ±1 from that of the analogous orthoNH3-CO state. This indicates that the lowest energy orientation of para-NH3-CO in the complex lies in a II configuration. The present results correlate very well with the only previous study of NH3-CO, in the microwave region, and clarify the nature of the rotational series observed there. The infrared band centre of NH3-CO is only very slightly shifted (<0.2cm−1) from that of the free CO molecule, indicating that the CO vibration has little effect on the intermolecular forces.

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
