Infrared emission spectroscopy of the [10.5]5Δ–X5Δ system of VF
Bibliographic record
Abstract
The emission spectrum of VF has been investigated in the 3400–17 000 cm−1 region using a Fourier transform spectrometer. The bands were excited in a high temperature carbon tube furnace from the reaction of vanadium metal vapor with CF4, as well as in a microwave discharge through a flowing mixture of VF4 vapor and helium. Several bands observed in the 9000–12 000 cm−1 region have been attributed to VF. The bands with high wave number R heads near 9156.8, 9816.4, 10 481.4, 11 035.8, and 11 587.2 cm−1 have been assigned as the 0-2, 0-1, 0-0, 1-0, and 2-0 bands, respectively, of the new [10.5]5Δ–X5Δ system of VF. A rotational analysis of the Δ15–Δ15, Δ25–Δ25, Δ35–Δ35, and Δ45–Δ45 subbands of the 0-1, 0-0, 1-0, and 2-0 bands has been carried out and spectroscopic parameters for VF have been obtained for the first time. The following equilibrium constants have been determined for the ground state of VF by averaging the constants of the different spin components: ΔG(1/2)=665.10 cm−1, Be=0.3863 cm−1, αe=0.0028 cm−1, and re=1.7758 Å.

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.
