Abstract

fetched live from OpenAlex

XeAgF and XeAgCl have been prepared by laser ablation of Ag metal in the presence of xenon and SF6 or xenon and Cl2, respectively. Rotational spectra for 12 isotopomers of XeAgF and 16 isotopomers of XeAgCl have been recorded. Analysis of the spectra indicates that (i) both chemical systems are unusually strongly bound compared to conventional van der Waals complexes, (ii) significant charge rearrangement occurs at the xenon nucleus upon formation of both XeAgF and XeAgCl as shown by the 131Xe nuclear quadrupole coupling constants and (iii) in both XeAgF and XeAgCl the Xe–Ag distance is small compared to the sum of the Xe van der Waals radius and the Ag+ ionic radius. An ab initio study of the two species has been performed. The combined experimental and theoretical investigations indicate that the Xe–Ag interaction is not easily described, but that there is some evidence for weak chemical bonding.

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.
