ChatGPT-4o returned some accurate information, but mentioned that the structure could include an oxygen "possibly an aldehyde", with other less accurate statements. 3.5 Sonnet returned an incorrect isomer, isoquinoline , and lacked detail seen in the three GPT models, although some broad chemical shift ranges for 1H-NMR and 13C-NMR resonances were correct. Gemini 1.5 Pro only satisfied the second condition, in which the model's generation order was similar to the spectra's order, with inaccurate information leading up to ethylamine as an incorrect answer, as reflected in Table . -The 13C-NMR is consistent with an aromatic system with multiple distinct carbon environments.
