Isotope shifts in the [10.1]4–<i>X</i>4 (0–0) and [10.5]3–<i>X</i>4 (0–0) transitions of NdOThis article is part of a Special Issue on Spectroscopy at the University of New Brunswick in honour of Colan Linton and Ron Lees.

Abstract
High-resolution Fourier transform thermal emission spectra of NdO (natural isotopic composition) have been recorded in the near infrared. Rotational analyses of the 0–0 band of the [10.132]4–X(1)4 system have been performed for all seven isotopomers, and the 0–0 band of the [10.506]3–X(1)4 system has been analysed for 142 NdO, 144 NdO, and 146 NdO. Experimental data have been merged into a global fit to obtain a unique set of isotopically consistent rotational spectroscopic constants, scaled to 142 NdO by assuming isotopic relationships within the Born–Oppenheimer approximation, but with independent band origins. These vibronic energy shifts reflect the isotopic shifts observed in some atomic lines also seen in the spectrum. A catalogue of experimental line positions and o−c values is available as Supplementary data.

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.
