Abstract

fetched live from OpenAlex

The fundamental and overtone absolute intensities of the perpendicular band of the isolated CH chromophore in chloroform (CHCl 3 ), bromoform (CHBr 3 ), and iodoform (CHI 3 ) have been calculated. The calculations were carried out by employing a three-dimensional curvilinear internal coordinate Hamiltonian and a polynomial expanded three-dimensional dipole moment surface (DMS). The DMS was obtained by a hybrid density functional method. Molecular symmetry was used to deduce the appropriate DMS expansion formulas. The calculated band intensities were compared with available experimental data. Most predicted values are accurate to within a factor of 2.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
