A comparative analysis of vibrational spectra for odorant classification
Fig 3
Classification of odorant compounds based on their Raman spectra.
Each spectrum is labeled according to the compound numbers listed in Tables I and II. The spectra are color-coded by group to enhance visual distinction. Group A’: methyl salicylate, (Z)-Methyl-p-methoxycinnamate, Benzoic acid, Acetophenone, Benzaldehyde. Group B’: (-)-α-Copaene, Eucalyptol, Octanal, 3-Methyl-2-pentanone, Heptanal, Decanoic acid. Group C’: Dimethyl disulfide, Dimethyl trisulfide. Group D’: (E,E)-α-farnesene, (E)-β-ocimene, Caryophylladienol II, (E)-Methyl-p-methoxycinnamate. Group E’: Indole. Group F’: linalool, (-)-β-Caryophyllene, β-Bisabolene, (E)-α-Bergamotene, 6-Methylhept-5-en-2-one, (E)-Geranyl geraniol, d-Limonene.
