Note: Molecular architecture dependent hydrogen-bonded motifs, entropy change, and dielectric permittivity of alcohols
Bibliographic record
Abstract
Our previous studies showed that the static permittivity, ɛs, of some octanol isomers first increased on cooling, then decreased, and finally increased rapidly, and ɛs monotonically increased on compression such that the local minimum in ɛs vanished. Thus, while ɛs is the same at different temperatures and pressures, the density differs. To reconcile these findings with thermodynamic requirements, we propose that hydrogen bonded ring-dimers of near zero dipole moment that form on initial cooling and decrease ɛs, open to form linear-dimers on further cooling (or pressurizing). The H and O atoms at the terminals of the linear dimer form hydrogen bonds with the existing monomers and linear chains, thus extending the length of the H-bonded chains. This mechanism agrees with the enthalpy and entropy of formation of ring-dimer and linear-chain motifs.

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.
