PeakAL: Protons I Have Known and Loved, Too — Another Fifty Shades of Grey-Market Spectra. Supplementary Data
Bibliographic record
Abstract
1H NMR spectra of 43 alleged psychedelic tryptamines (2-(1H-indol-3-yl)ethan-1-amines) and benzofuran analogues (2-(1-benzofuran-3-yl)ethan-1-amines) from grey-market internet vendors across North America and Europe were acquired and compared. Tryptamines having mono- or di- alkyl, cyclopropyl, or allyl amine substituents and/or substitution of the indole/benzofuran ring by acetyloxy, hydroxy, methoxy, or methyl groups were analysed. 1H NMR spectra for some of these compounds have not been previously reported to my knowledge. The spectrum of each analyte is consistent with the compound as labelled and sold. None of the analytes was found to be unequivocally misrepresented. This collection of experimentally uniform spectra may help forensic and harm-reduction organizations identify these compounds, some of which appear only sporadically. The complete spectra are provided as supplementary data.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
