High resolution spectroscopic analysis of the v2 = 1 and v4a = 1 states of 14ND2H
Bibliographic record
Abstract
Transitions of ND 2 H have been detected in the high-resolution spectra of 14 ND 3 recorded in the region 60 − 1515 cm −1 , using the Bruker IFS 125 Fourier transform spectrometer located at the synchrotron far-infrared beamline, Canadian Light Source. In this study we report on the observation and analysis of transitions to and between the s, a inversion levels of the v 2 = 1 and v 4a = 1 states for ND 2 H. We assigned to v 2 = 1 (v 4 a = 1) 996 (296) rotation-inversion transitions, with J up to 19 (13), and 3578 (1966) vibration-rotation-inversion transitions from the ground state, with J ′ up to 22 (13). The newly assigned transitions, together with those present in the literature, were fitted on the basis of a Watson-type S reduced Hamiltonian using the III l representation. The model includes terms up to the 10th power of the angular momentum and vibration-rotation interaction terms between the inversion levels. Precise and extended sets of spectroscopic parameters and term values were derived for the s, a v 2 = 1 and v 4 a = 1 states as results of least squares weighted fit procedures that reproduce the transition wavenumbers at experimental accuracy.

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.
