Planar nitrogen compared with planar carbon in a series of compounds: the effect of replacing with nitrogen the potentially planar tetracoordinate carbon of a series of polycyclic alkanes
Bibliographic record
Abstract
Previous work by Radom and Rasmussen had been extended by the author (E. Lewars. 2019. Can. J. Chem. 97(2): 154) to identify a smaller (C 17 H 16 cf. C 23 H 24 ) polycyclic alkane with a potentially planar tetracoordinate “central” carbon. Here, the series of alkanes in that latter study were computationally modified by replacing the central carbon with isoelectronic nitrogen, N + . A series of six ammonium ions was found by ab initio calculations to potentially all, with one exception, harbour a planar tetracoordinate nitrogen in a potential energy relative minimum at the MP2/6-31G* and MP2/(large basis) levels, as indicated by the absence of an imaginary vibrational frequency. This is in contrast to the hydrocarbons, where only two such structures were indicated to be relative minima.

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.
