Terahertz spectroscopy of CaH
Bibliographic record
Abstract
Calcium monohydride, CaH, has been a molecule of astrophysical interest ever since its first identification in sunspots. For astrophysical use it is therefore important to provide rest frequencies in the terahertz range. We observed pure rotational transitions for the υ = 0, and υ = 1 levels. This is the first report of pure rotational spectra of the υ = 1 level. We also performed a global fitting of the effective molecular constants for the υ = 0 to υ = 4 levels of the electronic ground state along with infrared transitions from previous studies. • Pure rotational transitions of CaH (X 2 Σ + ) were observed in the 0.25–3.87 THz region. • N values up to 15 and 16 were seen in the υ = 0 and 1 vibrational states, respectively. • Molecular constants were determined for the lowest vibrational states of CaH (X 2 Σ + ). • Accurate transition rest frequencies are provided. • A global analysis including vibrational transitions was also carried out.

How this classification was reachedexpand
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.
