The role of rotational relaxation in the intersystem crossing between a triplet and a singlet electronic state
Bibliographic record
Abstract
Abstract A calculation of the rate of ISC (intersystem crossing) relaxation at 0 K requires a knowledge of the spin–orbit coupling and the vibrational overlap integrals (Franck‐Condon factors) between the T1 and S0 states. At elevated temperatures, the population of the rotational states needs to be taken into account through the overlap of the rotational wavefunctions between the interacting T1/S0 electronic states. Here, we discuss the effect of the ISC singlet–triplet selection rules on the number and magnitude of the rotational overlap factors for the J = 0, 5, and 10 rotational levels of thiophosgene, Cl2CS. Of equal importance is the influence of the spin–spin and spin‐rotation coupling on the rotational fragmentation factors and the ISC survival probability. © 2010 Wiley Periodicals, Inc.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
