Abstract

fetched live from OpenAlex

Abstract Three-dimensional time-dependent Schrodinger equation simulations of Raman excitation of the Cl 2 molecule are used to demonstrate the feasibility of efficient high vibrational excitation ( v ⩾20) of symmetric non-polar bonds using short (ps) chirped frequency laser pulses at intensities below the ionization threshold ( I=2×10 13 W/cm 2 ). The process called chirped adiabatic Raman passage (CARP) involves sequential Raman excitations Δv =+1 during the pulse accompanied by rotational transitions. It is shown that as a result of CARP, considerable laser alignment of the molecule is achieved in high vibrational levels, thus offering a new tool for the study of dynamics and reactivity of aligned excited molecules.

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.
