Abstract
Abstract Laser‐flash photolysis techniques were applied to investigate the dependence of the rotational barrier about the N‐2—N‐3 bond of symmetrically 4,4′‐disubstituted cis ‐1,3‐diphenyltriazenes on substituents and solvents. The increase in the rotational barrier with increasing ability of the 4‐substituent to withdraw electrons implies the intramolecular process to be more susceptible to the electronic character of the aryl group attached to N‐1 than of that bonded to N‐3. Furthermore, the increase in the rotational barrier with decreasing solvent polarity implies an increase in dipole moment on rotation from the ground state to the transition state.

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 it
