Stark field induced perturbations in the ν2+3ν3 vibrational overtone band of acetylene
Bibliographic record
Abstract
The ν2+3ν3 vibrational overtone of acetylene was recorded using an optothermal molecular beam spectrometer. The sample excitation region was surrounded by a build-up cavity and by electrodes which allowed the observation of Stark splittings of the spectral transitions. An analysis of the J dependence of the splittings determined that the (01300)0 is mixed by the Stark field with the IR (infrared) dark state (11200)0, and that the energy of the ν1+ν2+2ν3 transition is 11 611.585±0.018 cm−1. The spectra also showed transitions to highly excited bending levels: These transitions were observable because they borrowed intensity from the more intense ν2+3ν3 stretching overtone as they were tuned into coincidence. The bending states were found to have extremely high polarizabilities which may account for previously reported collision dynamics.

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.
