As shown in the author's prior study with complex molecules, models introduced with a text prompt and many spectral images contained too much context and were not optimal for generating accurate solutions. In the previous case, only a simpler C 9 H 7 N compound, quinoline, was obtained by three OpenAI GPT variants with combined prompt and image uploads due to less complex 1H-NMR and DEPT-NMR spectra, lack of stereochemistry or diastereotopic protons, and lack of 2D NMR discrepancies . In this study, spectral parameters were not included in images, as attention was taken away from LMM results based on preliminary results.
