Abstract

fetched live from OpenAlex

Abstract Employing the recent XC(fit) intermolecular potential for H2‐Ar, we have presented the results of the spectral parameters for the D2‐Ar Raman Q1 branch, obtained from quantum mechanical close‐coupled calculations. While the theoretical line shifts of the polarized Raman spectra were found to agree with experiments, the corresponding widths were smaller than the measured values by as much as 56%. We observed that the shifts and the widths depend on the vibrational dependence of the potential in their own separate ways, and our results suggested that the anisotropic vibrational dependence of the XC(fit) potential requires improvement, in conjunction with further fine‐tuning of the isotropic part. Even though there is no experimental data for comparison, we have computed the line‐mixing parameters of the polarized Raman Q1 branch, as well as the depolarized line widths and shifts for the Q1(j) lines. These results showed the same trends as the corresponding ones for D2‐He.

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.
