Photodissociation of hydrogen iodide in the A-band region 273–288 nm
Bibliographic record
Abstract
The photodissociation of hydrogen iodide in the A-band region was investigated between 273 and 288 nm using the photofragment imaging technique. At 17 wavelengths the I* (2P1/2)/I(2P3/2) branching ratio was measured by recording the corresponding hydrogen atomic fragment using multiphoton ionization at 243 nm. The branching ratios are in good agreement with previous measurements and confirm that four (final) states Π3(0+), 3Π(1), 3Σ(1), and Π1(1) are involved in the A-band absorption of HI and that those states dissociate adiabatically to form H+I* and H+I following parallel and perpendicular transitions, respectively. The deficiency of the model of three unbound states and that of the δ-approximation is substantiated.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
