Abstract
Magnetic-field dependence of the interaction tensors of the nuclear magnetic resonance spin Hamiltonian has been experimentally observed in one case so far, in the 131Xe quadrupole coupling of atomic xenon in isotropic gas and liquid phases. We revisit the problem both computationally and experimentally. First-principles electronic structure calculations are carried out at the four-component relativistic Dirac–Hartree–Fock and Dirac-density-functional levels of theory, as well as at various non-relativistic levels using novel, completeness-optimised basis sets. The results are compared to earlier theory, where relativistic effects were considered perturbationally, as well as to experimental data. New measurements of the 131Xe spectrum in the gas phase at natural abundance are reported. The new calculations and experiments provide improved numerical precision as compared to the earlier data, and are in good agreement with each other.

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
