Far-IR Spectra and Structures of Small Cationic Ruthenium Clusters: Evidence for Cubic Motifs
Bibliographic record
Abstract
Far-IR vibrational spectra of small ruthenium cluster cations (Ru 7 +, Ru 8 +, and Ru 9 + ) are measured via infrared multiple photon dissociation (IR-MPD) spectroscopy using Ar atoms as messenger for the absorption. These spectra are compared to results from density functional theory calculations, leading to structural assignments. The pure functional PBE leads to better agreement with the experimental data compared to the hybrid functional PBE0. For all three cluster sizes the structures assigned are based on a cubic motif and are a distorted cube missing one corner atom (Ru 7 + ), a slightly distorted cube (Ru 8 + ), and a face-capped cube (Ru 9 + ).

Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
