Abstract
Abstract A comparative investigation of the molecular orientation of copper phthalocyanine on the surfaces of Ge(001)‐2 × 1 and Ge(111)‐c(2 × 8) is presented. As a first step, intrinsic NEXAFS spectra are established through a combination of the computational technique of DFT and an experiment of a well ordered monolayer film on the weakly interacting highly oriented pyrolytic graphite substrate. This reveals σ * intensity in the usual π* region, which is excluded in subsequent analysis of the orientation of molecules. At monolayer coverage the molecules lie close to parallel to the substrate, whereas in a thin film they tend towards perpendicular to the substrate. On the more weakly interacting Ge(111) surface the orientation is more extremal for both monolayer and thin film, indicating possible contributions from both disorder and an adsorption‐related extrinsic effect on Ge(001).

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
