Results from generative AI were likely impacted by multiple unidentified 1H-NMR resonances from the authors' paper, including unlabelled NH2 resonances seen in Figure . The 13C-NMR and DEPT-135 spectra correspond to the authors' structure, but were not interpreted well by the LMMs tested. GPT-5 did provide a useful double bond equivalent calculation, and was the only model to comment on the 1H-NMR narrowed view spectrum. ChatGPT-4o, Organic Chemistry, and 3.5 Sonnet had inconsistencies in reaching conclusions from the spectra, as depicted in 3.5 Sonnet's abbreviated generation.
