Computer Simulation Study of <i>tert</i>-Butyl Alcohol. 1. Structure in the Pure Liquid
Bibliographic record
Abstract
MD simulations of neat liquid tert -butyl alcohol (TBA) are carried out. Two very different potential models have been constructed for TBA: a simple rigid three-site model and a fully flexible all-atom 15-site model, with the O−H stretching described with an anharmonic potential well. Pure liquid TBA is investigated to evaluate the two potential models and to study the liquid structure in more detail. An analysis based upon both radial distribution functions and spatial distribution functions is employed. Generally it is found that the 15-site model is superior, providing reasonable agreement with experimentally derived data, while the three-site model is only able to reproduce qualitatively the competitive hydrophobic and hydrophilic aspects of the intermolecular interactions. Overall the structures observed reflect a frustrated hydrogen-bonded system.

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.
