Abstract
Smog chamber/FTIR techniques were used to measure (Cl + n- C x F 2 x +1 CHO, x = 1, 3, 4) = (2.1 ± 0.5) × 10 -12 and k (OH + n- C x F 2 x +1 CHO, x = 1, 3, 4) = (6.5 ± 1.2) × 10 -13 cm 3 molecule -1 s -1 in 700 Torr of N 2, or air, at 296 ± 2 K. Cl-initiated oxidation of n- C x F 2 x +1 CHO in the presence of NO in air diluent gave COF 2 in molar yields of 91 ± 11%, x = 1; 273 ± 36%, x = 3; and 371 ± 44%, x = 4. Small quantities (molar yields ≤ 3%) of CF 3 ONO 2 and n- C x F 2 x +1 C(O)O 2 NO 2 were also observed. IR spectra of n- C x F 2 x +1 C(O)O 2 NO 2 ( x = 1, 3, 4) are reported. Results are discussed with respect to the atmospheric degradation of fluorinated aldehydes, C x F 2 x +1 CHO.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
