Organic monolayers detected by single reflection attenuated total reflection infrared spectroscopy
Bibliographic record
Abstract
A single-reflection attenuated total reflection (ATR) technique has been used to study low index monolayers with a high index ATR hemisphere in an optical contact with the sample surface. A model calculation predicts a field enhancement with the present method substantially larger than that of conventional ATR. For the present method, a discontinuity of the field normal to the film is responsible for the field enhancement in the lower index thin film. We show theoretically and experimentally that the angle of incidence has a strong influence on the ATR signal strength. We demonstrate the present method by examining the infrared reflectance spectra of a undecylenic acid self-assembled on Si (111) and with the adsorption of a bovine serum albumin monolayer. We also apply the method to examine the oxidation and surface contamination of the functionalized Si samples stored in ambient conditions.

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.
