Abstract
The infrared spectra of H3+ and D3 were first observed almost simultaneously in 1980. Since then there has been extensive laboratory work on H3 and its D-isotopomers. In addition, the spectrum of H3+ has been observed in emission from the atmospheres of the giant planets Jupiter, Saturn and Uranus, and probably from the supernova SN1987A, and recently in absorption in interstellar clouds. In this introductory paper, the assignment of the spectra and some of the characteristic features associated with the strong anharmonicity are discussed. As the convergence of the perturbation series is poor, the large centrifugal effects are best calculated in a variational type of approach, where the rotational energy in the Hamiltonian can be treated essentially exactly. Ab initio calculations have steadily improved over the years, and recent work has given completely theoretical vibration–rotation term values for the low vibrational states with an accuracy better than 0.1 cm-1 in almost all cases, adequate for most spectroscopic assignment purposes.

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.
