Abstract
We are reporting the fluorescence quenching, IR, Raman, 1H-NMR, and potentiometric studies for the Zn2+:adenine and the Cd2+:adenine systems under ambient conditions. IR and Raman spectra suggest that Zn2+ and Cd2+ interact with adenine but the modes of interaction differ. Fluorescence spectra indicate that the interaction involving Zn2+ is more favorable than that of Cd2+, and this effect is due to the difference in ionic radii. 1H-NMR, potentiometry, and speciation diagrams indicate the formation of strong metal ion adenine complexes. Potentiometric titrations of the heavier member of group 12 metals (Hg2+) show similar results to that of Zn2+ and Cd2+. Some differences in the 1H-NMR experiments appeared between both (Zn2+ and Cd2+) compared to that of Hg2+. Due to the fluorescence quenching of adenine, adenine can be used as a sensor of Zn2+ and Cd2+.

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
