Computational Study on the Absorption Mechanisms of SO <sub>2</sub> by Ionic Liquids
Bibliographic record
Abstract
Abstract A density functional theory study was conducted to explore the absorption mechanisms of SO 2 by ionic liquids (ILs), including task specific ILs 1,1,3,3‐tetramethylguanidinium lactate ([TMG][LAC]), and normal ILs 1‐butyl‐3‐methylimidazolium tetrafluoroborate ([BMIM][BF 4 ]) and 1‐butyl‐3‐methylimidazolium hexafluorophosphate ([BMIM][PF 6 ]). The strength of chemical absorption by [TMG][LAC] is stronger than physical absorption, and the physical absorption energy follows the order of [TMG][LAC] > [BMIM][BF 4 ] > [BMIM][PF 6 ]. Other than O⋅⋅⋅H hydrogen bonding, S⋅⋅⋅O interactions are important for [TMG][LAC] physical absorption of SO 2 , and S⋅⋅⋅F interactions are critical for SO 2 absorption by [BMIM][BF 4 ] or [BMIM][PF 6 ]. Both anions and cations of ILs contribute to the physical absorption of SO 2 . [TMG] + plays an important role in the chemical reaction between SO 2 and [TMG][LAC]. The proton transfer reaction barrier between 1,1,3,3‐tetramethylguanidine and lactic acid is 1.176 kcal/mol.

How this classification was reachedexpand
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.
