Abstract

fetched live from OpenAlex

The van der Waals complex NH3-N2 has been studied in the millimetre wave region, 76–106 GHz. Thirty-five lines were observed and assigned as pure rotational transitions, R(11) to R(15), belonging to six series involving all combinations of the parent molecule nuclear spin species, ortho/para-ammonia and ortho/para-nitrogen. Two of these series are continuations to higher J values of transitions observed previously in the microwave region, and the other four series were observed here for the first time. Predictions are given for a number of new NH3-N2 microwave transitions, and future observations of these should help to confirm the assignments given here. The time is ripe for theoretical investigations of NH3-N2 and the isoelectronic complex NH3-CO.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
