Abstract
The 2-carbazolylnitrenium ion and its 9-methyl analog have been investigated by laser flash photolysis. These electrophiles were generated by irradiation of 2-azido-9H-carbazole and 9methyl-2-azido-9H-carbazole in solutions of 20% acetonitrile in water. Kinetic and spectral evidence is presented for three forms of the 2-carbazolylnitrenium ion, the monocation, its dication conjugate acid and a neutral quinonoid-like conjugate base obtained by loss of the 9-NH proton. The 9-methyl system, which cannot form the neutral species, exists as dication and monocation. Acidity constants relating the various forms and rate constants for their reaction with water, bromide ion and azide ion are obtained by kinetic analyses.

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
