Fourier transform infrared emission spectroscopy of VCl
Bibliographic record
Abstract
The high resolution spectrum of VCl has been observed in emission in the 3000–9400 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 and a trace of BCl3 and the spectra were recorded at a resolution of 0.05 cm−1. The new bands observed in the 6000–8000 cm−1 interval have been attributed to VCl. The bands having R heads near 6176, 6589, 7004, 7358, and 7710 cm−1 have been assigned as the 0–2, 0–1, 0–0, 1–0, and 2–0 bands, respectively, of the [7.0]5Δ–X 5Δ electronic transition. A rotational analysis of the Δ15–Δ15, Δ25–Δ25, and Δ35–Δ35, subbands of the 0–1 and 0–0 vibrational bands has been obtained and molecular constants have been extracted. The remaining two of the five subbands could not be analyzed because of severe overlapping from neighboring subbands. The principal molecular constants for the X 5Δ state obtained from the present analysis are: ΔG(1/2)=415.26(113) cm−1, Be=0.165 885(250) cm−1, αe=0.000 586(84) cm−1, and re=2.213 79(170) Å. Our work represents the first observation of this near infrared electronic transition of VCl.

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.
