GPT-5 reported the most accurate 1H and 13C-NMR chemical shift ranges: "Aromatic Region (6.5 -8.5 ppm)" and "Signals in the region of 120-150 ppm", shown in Figure ." Although most of the explanation was accurate, there was an error referencing hydrogen atoms of the correct structure. Organic Chemistry gave accurate evidence, such as "the spectrum shows 9 distinct carbon signals, consistent with the nine carbon atoms in quinoline", but reported inaccurate chemical shifts.
