Abstract
The rovibrational spectra of \\chem{N_2-D_2O} and \\chem{N_2-DOH} were measured around the \\chem{OD} stretching region. A combination band involving the in-plane \\chem{N_2} bend intermolecular vibration was also observed in the same frequency range. These bands were measured at the University of Calgary using a pulsed-slit supersonic jet expansion and a mid-infrared tunable optical parametric oscillator. The spectra were analyzed by considering the feasible tunneling motions and fit to a series of independent asymmetric rotors. The rotational constants of the four tunneling components of \\chem{N_2-D_2O} were retrieved for the excited vibrational states. Small vibrational blue shifts of $0.6~\\wn$ and $1.8~\\wn$ compared to the \\chem{D_2O} monomer band origins were determined for the symmetric and asymmetric stretches, respectively. A two order of magnitude larger tunneling splittings is observed for the asymmetric \\chem{OD} stretching excitation compared to the symmetric one. This last finding indicate a significant change of the intermolecular dynamics due to the intramolecular asymmetric \\chem{OD} vibration.

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.
