Estimation of relaxation times during free evolution from the SECSY signal of an electron-nuclear spin-coupled system in a γ-irradiated malonic acid single crystal
Bibliographic record
Abstract
Abstract The relaxation times T 2 ,' characterizing the allowed and T 2 '', characterizing the forbidden and coherence cross resonances, during free evolutions over the coherent pathways p = ±1 are estimated from the SECSY (Spin Echo Correlation Spectroscopy) signal of the electron-nuclear spin-coupled system in a γ-irradiated malonic acid single crystal. This is accomplished by fitting the intensities of the two main peaks in the Fourier transform of the SECSY signal reported by Lee, Patyal and Freed (J. Chem. Phys. 98, 3665 (1993)) to T 2 ' and T 2 ''. The values of the fitted relaxation times T 2 '=500 ns, T 2 "=50,000 ns, reveal that the relaxation via the allowed resonance is two orders of magnitude faster than that via the forbidden and cross resonances. Full details of the calculation exploiting the Liouville von Neumann equation are presented. PACS: 76.30.-v, 76.70.Dx

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.
