Abstract
We report observation of new infrared bands of \\chem{(CS_2)_2} and \\chem{(CS_2)_3} in the region of the \\chem{CS_2} \\nub{1} + \\nub{3} combination band (at 4.5 $\\mu$m) using a quantum cascade laser. The complexes are formed in a pulsed supersonic slit-jet expansion of a gas mixture of carbon disulfide in helium. We have previously shown that the most stable isomer of \\chem{(CS_2)_2} is a cross-shaped structure with \\chem{D_{2d}} symmetry and that for \\chem{(CS_2)_3} is a barrel-shaped structure with \\chem{D_3} symmetry. The dimer has one doubly degenerate infrared-active band in the \\nub{1} + \\nub{3} region of the \\chem{CS_2} monomer. This band is observed to have a rather small vibrational shift of -0.846 \\wn. We expect one parallel and one perpendicular infrared-active band for the trimer but observe two parallel and one perpendicular bands. Much larger vibrational shifts of -8.953 \\wn for the perpendicular band and -8.845 \\wn and +16.681 \\wn for the parallel bands are observed. Vibrational shifts and possible vibrational assignments, in the case of the parallel bands of the trimer, are discussed using group theoretical arguments.

How this classification was reachedexpand
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.
