Abstract

fetched live from OpenAlex

Infrared spectra in the wavenumber ranges 100–1800 and 2700–4800 cm−1 are reported for bromoform samples in diamond anvil cells at ambient temperature and at pressures up to 10 GPa. The freezing pressure is estimated to be 0.13 ± 0.02 GPa. The spectra appear to evolve smoothly and no major discontinuities are detected. The dependence on pressure of eleven peak wavenumbers (five fundamentals and six combinations) is presented. All modes show small percentage increases in wavenumber over this pressure range, except for the degenerate bend, ν6, which exhibits a 20% increase, suggesting that the equilibrium Br-C-Br angles may be slightly changing with increasing pressure.

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.

Full frame distilled prediction

Teacher imitation

Not 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.
