Abstract

fetched live from OpenAlex

Direct bonding has been observed to occur between SiF 3 + and the rare gases xenon, krypton, and argon in the gas phase at low collision energies and, in the case of xenon and krypton, also at high collision energies. The kinetics of low-energy addition have been monitored at room temperature in He buffer gas at 0.35 Torr using the selected-ion flow tube (SIFT) tandem mass-spectrometer technique. An investigation of the energetics of dissociation of the adduct ions in multi-collision induced dissociation experiments revealed the formation of adduct ions at high collision energies. Experimental and theoretical results are presented for the formation and stability of two possible low-energy isomers of the gaseous trifluorosilylxenon cation, F 3 SiXe +, one formed by the direct bonding of Xe to Si and the other by Xe being attached to one F atom. Two possible high-energy isomers are proposed that contain a Si−Xe−F linkage formed by the insertion of Xe into SiF 3 + or a F−Xe−F linkage formed by bond redisposition. The carbon analogue CF 3 + did not form adduct ions with Xe under the same experimental conditions. Analogous experimental and theoretical studies are reported for the reactions of SiF 3 + with Kr and Ar. Experimental results also are reported for the reaction of SiF 3 + with N 2 and O 2 .

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.
