Circular Dichroism of Trigonal Dihedral Chromium(III) Complexes: A Theoretical Study based on Open-Shell Time-Dependent Density Functional Theory
Bibliographic record
Abstract
Spin-unrestricted time-dependent density functional theory has been applied to the electronic circular dichroism spectra of Cr(III) complexes with an open-shell ground state, that is, [Cr(L-L)(3)](n+) with L-L = en(ethylenediamine), acac(acetylacetonate), ox(oxalate), mal(malonate), and Thiox(dithiooxalate). The simulated CD spectra are analyzed in details and compared with experimental data, as well as previous calculations on similar Co(III) complexes where available. The theoretical results serve as a tool for elucidating the absolute configuration of similar complexes, by pointing to transitions for which the sign of the rotatory strength can be used as fingerprint for one particular configuration.

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.
