Determination of ro-vibrational excitations of N<sub>2</sub>(B, v′) and N<sub>2</sub>(C, v′) states in N<sub>2</sub> microwave discharges using visible and IR spectroscopy
Bibliographic record
Abstract
UV–visible and infrared (IR) emission spectroscopy measurements were performed in a N2 microwave discharge at pressures between 0.1 and 3 Torr and powers of 200 and 300 W. Although emission spectroscopy in the IR region has rarely been investigated, this technique has nevertheless provided numerous key data. The plasma temperature as a function of pressure was measured using the rotational transitions of N2(B, 2–A, 0) in the N2 discharge. In addition, the vibrational distribution of the N2(B, v′ = 0–3) states was measured by means of IR emission spectroscopy. These experiments confirmed that the excitation of these states occurred primarily through electron collisions on the N2(A) metastable molecules.

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.
