Spectra of CO<sub>2</sub>‐Kr in the 4.3 μm region: Intermolecular Bend and Symmetry Breaking of the Intramolecular CO<sub>2</sub> Bend
Bibliographic record
Abstract
Abstract The infrared spectrum of CO 2 ‐Kr complex is studied in the region of the carbon dioxide ν 3 fundamental vibration (≈2350 cm −1 ). Tunable IR radiation from an OPO is employed to record absorption spectrum of the complex generated in a pulsed supersonic slit jet. The spectrum exhibits broadening and splitting of transitions due to mass dependence of the five Kr isotopes with natural abundances exceeding 2 %. Good simulation of the spectrum is achieved by scaling the vibrational and rotational parameters. This scaling model is particularly important for the combination band involving the intermolecular bending mode where many isotope splittings are observed. As with other CO 2 ‐rare gas complexes, we also observe weak hot bands of CO 2 ‐Kr transitions corresponding to the hot band originating in the CO 2 intramolecular bend. From these we determine a splitting of 1.418 cm −1 between the in‐plane and out‐of‐plane bend of CO 2 , due to the neighboring Kr atom.

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.
