Spectra of jet-cooled SO232 and SO234 in systems ã 3B1 and b 3A2–X 1A1: Rotational structure of perturbed b 3A2
Bibliographic record
Abstract
Spectra of ã 3B1(ν1ν2ν3)=(110) and (200)–X̃ 1A1(000) of SO232 and SO234 are obtained in a supersonic jet at a resolution 0.015 cm−1. The rotational structures are analyzed for both isotopic species to obtain precise rotational and spin constants. Two new bands at 27 032.222(1) and 27 515.41(1) cm−1 arising from vibronic interaction separately with vibrational state (110) and (200) of ã 3B1 are assigned to transitions to b̃ 3A2(011) and (101). The rotational structure of b̃ 3A2 is observed and analyzed for the first time. The two vibrational states are analyzed to yield effective rotational constants A=1.4348(3), 1.89(3), B=0.3610(3), 0.412(3), and C=0.2689(3), 0.239(3) cm−1, respectively. Then the difference ν1−ν2 of vibrational frequency of b̃ 3A2 is obtained to be 483.19 cm−1. Because of interaction to b̃ 3A2(011) the observed spacing of K stack and spin constants α and β for ã 3B1(110) are smaller whereas the state ã 3B1(200) is relatively unaffected and only spin constants vary significantly.

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.
