Dynamic solvent effects on the fading of a merocyanine formed from a spironaphthoxazine. A case of a strong coupling between chemical and medium coordinate
Bibliographic record
Abstract
The pressure dependence of the rate constant for the fading of a merocyanine formed from a spironaphthoxazine was measured in three pairs of nonviscous/viscous solvents of similar polarity, such as ethanol/2-methylpentane-2,4-diol, methyl acetate/glycerol triacetate, and methylcyclohexane/2,4-dicyclohexyl-2-methylpentane. The results unequivocally demonstrated a necessity to treat the medium and the chemical coordinate as two independent coordinates. These coordinates were found strongly coupled in the present reaction, especially in protic solvents. The results also revealed that hydrogen-bond solvation to the oxygen atom in the initial state and its desolvation during the activation step play important roles in both reaction mechanisms and 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.
