Abstract

fetched live from OpenAlex

The weakly-bound van der Waals complex OCS–He has been observed by infrared spectroscopy in the region of the OCS ν1 vibration (≈2062 cm−1) in a pulsed supersonic jet expansion using a tunable diode laser probe. The results are in good agreement with previous microwave observations of OCS–He, but they extend to the vibrationally excited state, as well as to a considerably larger number of rotational levels with higher J-values. Prominent a-type transitions (ΔK=0) are observed, together with weaker b-type transitions (ΔK=±1). The rotational energy level pattern in the excited vibrational state is quite similar to that in the ground state, and the band origin is slightly blue-shifted (+0.111 cm−1) from that of the free OCS molecule. These results are of special interest due to recent observations in the same spectral region of OCS molecules trapped in ultra cold helium droplets.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
