Electronic structure of SrO molecules with dipole moments and ro-vibrational calculations
Bibliographic record
Abstract
Ab initio calculations have been applied to investigate the electronic structure of the SrO molecule. The potential energy curves have been computed in the Born–Oppenheimer approximation for the ground, and the 29 low-lying singlet and triplet excited electronic states. Complete active space self-consistent field, multi-reference configuration interaction have been utilized to investigate these states. The harmonic frequency ωe, the internuclear distance Re, the rotational constant Be, and the electronic energy with respect to the ground state Te have been calculated by using two different techniques of calculation with different bases. The transition dipole moment between some doublet states is used to determine the Einstein spontaneous A21 and induced emission [Formula: see text] coefficients as well as the spontaneous radiative lifetime τspon, emission wavelength λ21 and oscillator strength f21. The eigenvalues Ev, the rotational constant Bv, the centrifugal distortion constant Dv, and the abscissas of the turning points Rmin and Rmax have been calculated by using the canonical functions approach. The comparison between the values of the present work and those available in the literature for several electronic states shows a very good agreement. Twenty-four new electronic states have been studied here for the first time.

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.
