Abstract
An examination of the dynamical behavior of H + HD and D + H\u2082 in the ground electronic state is performed on the BKMP2 potential energy surface using the quasiclassical trajectory method. The complete set of state-to-state energy transfer and state-specific dissociative cross sections and thermal rate coefficients has been obtained for both systems. Comparisons are made to the H + H\u2082 system to investigate isotopic effects on reactivity and energy transfer. Collision-induced dissociation, exchange reactions, and non-reactive energy transfer are analyzed and compared to previous results on this system, when such are available. As a prototypical three-body system, H + H\u2082 and its isotopic analogues are interesting as benchmarks for both theoretical and experimental methods. The results of this work can be applied to the general field of molecular reaction dynamics, to interstellar physics and chemistry, to models of planetary atmospheres and stellar system formation, and to studies of the effects of isotopes on reaction rates. The work is motivated by astrophysical applications: in particular, the data may be used as inputs for master equation calculations for interstellar gases.

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.
