Photoinduced localized atomic reaction (LAR) of 1,2- and 1,4-dichlorobenzene with Si(111) 7×7
Bibliographic record
Abstract
We report a comparative study of the photoinduced localized atomic reaction, LAR, of 1,2- and 1,4-dichlorobenzene (1,2- and 1,4-diClPh) on Si(111) 7×7, studied by scanning tunneling microscopy (STM). We observe different chlorine nearest-neighbor separations for the Cl–Si photoformed chemical “imprints” for the two adsorbates; the most probable separation of neighboring Cl’s in the case of 1,2-dichlorobenzene being 8±3 Å, whereas that for 1,4-dichlorobenzene is 14±3 Å. These differing separations can be understood if the two C–Cl bonds in the respective adsorbates extend roughly linearly to chlorinate a nearby Si dangling-bond; for 1,2 diClPh the two C–Cl bonds are at 60° to one another leading to the chlorination of closely neighboring Si, whereas for 1,4 diClPh the two C–Cl bonds are at ∼180° leading to chlorination of sites twice as far apart, located to either side of the 1,4 diClPh adsorbate.

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.
