The ν<sub>1</sub> and ν<sub>2</sub> vibrational bands of the OCCN radical detected through time-resolved Fourier transform IR emission spectroscopy
Bibliographic record
Abstract
Through monitoring the IR emission from vibrationally excited radicals generated by exothermic photolysis reactions, the CN stretch (ν 1 ) and the CO stretch (ν 2 ) vibrational bands of the cyanooxomethyl radical (OCCN) have been observed for the first time at 2093 cm 1 and 1774 cm 1 , respectively. The OCCN radical was produced through 193 nm photolysis of methyl cyanoformate (NCC(O)OCH 3 ), carbonyl cyanide (NCC(O)CN), and pivaloyl cyanide (NCC(O)C(CH 3 ) 3 ). The IR emission spectra were recorded by using nanosecond time-resolved Fourier transform IR emission spectroscopy. Assignments of the spectral peaks were made based on observed time and pressure dependences of IR emission intensities, ab initio calculations, and two-dimensional cross-spectra correlation analysis. Key words: radical, cyanooxomethyl, OCCN, time-resolved vibrational spectroscopy, FTIR, substituted carbonyl dissociation reactions, two-dimensional cross-spectra correlation analysis

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.
