Example spectra:A single caffeine MS/MS spectrum (MassBank reference standard) - the quick exact-match demo.A single theophylline MS/MS spectrum (MSnLib reference standard) - a methylxanthine positional isomer of theobromine, close enough to caffeine to test whether ranking tells structural relatives apart rather than only exact matches.A single quercetin MS/MS spectrum (MassBank reference standard) - a common plant flavonoid, positive mode only, the single-molecule natural-product demo.
