Abstract
Abstract Resonance Raman optical activity (RROA) is commonly measured as the difference in intensity of Raman scattered right and left circularly polarized light, I R −I L , when a randomly polarized light is in resonance with a chiral molecule. Strong and sometimes mono‐signate experimental RROA spectra of several chiral solutes were reported previously, although their signs and relative intensities could not be reproduced theoretically. By examining multiple light‐matter interaction events which can occur simultaneously under resonance, we show that a new form of chiral Raman spectroscopy, eCP‐Raman, a combination of electronic circular dichroism and circularly polarized Raman, prevails. By incorporating the finite‐lifetime approach for resonance, the experimental patterns of the model chiral solutes are captured theoretically by eCP‐Raman, without any RROA contribution. The results open opportunity for applications of eCP‐Raman spectroscopy and for extracting true RROA experimentally.

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 it
