1H NMR spectra of classical and novel psychoactive substances (NPS) are reported, including
- phenylethanamines (2-phenylethan-1-amines),
- phenylpropanamines (1-phenylpropan-2-amines),
- N-benzyl-phenylalkanamines,
- β-keto-phenylalkanamines (2-amino-1-phenylethan-1-ones and 2-amino-1-phenylpropan-1-ones),
- thiophenylpropanamines (1-(thiophen-2-yl)propan-2-amines),
- phenmetrazines (3-methyl-2-phenylmorpholines),
- aminoindanes (2,3-dihydro-1H-inden-2-amines),
- tryptamines (2-(1H-indol-3-yl)ethan-1-amines),
- aminorexes (4,5-dihydro-1,3-oxazol-2-amines), and
- others.

1H NMR spectra of 43 alleged psychedelictryptamines (2-(1H-indol-3-yl)ethan-1-amines) andbenzofuran 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.

1H NMR spectra of 28 alleged psychedelic phenylethanamines from 15 grey-market internet vendors across North America and Europe were acquired and compared. Members from each of the principal phenylethanamine families were analyzed: elevenpara-substituted 2,5-dimethoxyphenylethanamines (the2C and2C-T series); fourpara-substituted 3,5-dimethoxyphenylethanamines (mescaline analogues); twoβ-substituted phenylethanamines; and tenN-substituted phenylethanamines with a 2-methoxybenzyl (NBOMe), 2-hydroxybenzyl (NBOH), or 2,3-methylenedioxybenzyl (NBMD) amine moiety.1H NMR spectra for some of these compounds have not been previously reported to our knowledge. Others have reported on the composition of "mystery pills," single-dose formulations obtained from retail shops and websites. We believe this is the first published survey of bulk "research chemicals" marketed and sold as such. Only one analyte was 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.
