Abstract
The transverse (TO) and longitudinal (LO) optical phonons in bulk alloys of InP1−xAsx at room temperature have been studied previously by Kekelidze et al. [J. Phys. Chem. Solids 34, 2117 (1973)] using infrared reflectance spectroscopy. Their analysis based on the classical model yielded results that indicated a linear dependence on composition for all four optical modes, but no actual mode frequencies were reported. We have reanalyzed their spectra using three different methods: the conventional Kramers-Kronig approach, the factorized model fitted to the differential of the reflectivity, and directly fitting the reflectivity. The results obtained for the mode frequencies are found to vary somewhat depending on the method used, but the two LO modes are seen to exhibit a slight nonlinear dependence on x. The results also provide information on the concentration dependence of the damping of the InP-like and InAs-like TO and LO phonons. The InP-like and InAs-like mode oscillator strengths have also been determined and are found to vary differently from that depicted schematically earlier by Kekelidze et al. Comparisons are made with infrared reflectivity results obtained earlier by Oswald [Z. Naturforsch. A 14A, 374 (1959)].

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
