Semiclassical and quantum-mechanical study of the reaction mechanism for the N<sub>2</sub> + N<sub>2</sub><sup>+</sup> electron transfer system
Bibliographic record
Abstract
Density functional theory (DFT) calculations, including electron correlation, were carried out on the N2 + N2+ electron transfer system. Six geometries of the precursor complex were assumed and their stabilities were calculated and compared. The activation energy, the electronic transmission factor, and the electronic coupling matrix element in the electron transfer process were also calculated. The electronic transmission factor for this system was far less than unity (ca. 0.006~0.09); thus, the electron transfer reaction was considered to be diabatic in nature. Therefore, the electron transfer rate for the selected structures was calculated using semiclassical and quantum-mechanical theories. The calculated values were compared with each other and were in good agreement with the experimental value.Key words: N2 + N2+ electron transfer reaction, semiclassical and quantum-mechanical theories, electronic transmission factor, electronic coupling matrix element, B3LYP.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
