ChatGPT-4o did not provide adequate detail for the 1H-NMR spectra, and 13C-NMR chemical shifts were also not accurate. GPT-5 provided a helpful double bond equivalent calculation, and was the only model to explicitly refer to the lower 1H-NMR spectrum. However, 1H-NMR and 13C-NMR chemical shifts were not completely accurate, and some of the identified moieties were not correct.
