Table 2 Molecules with their Perceptual classes and the dominant vibrational modes (in cm−1) identified by peak-decomposition of EVA pseudo-spectrum. A, B: Low-frequency torsional modes. C, D: Ring torsion and C–H rocking. E, F: Ring deformation, C–H wagging, and C–C stretch. G: C=C stretch. H: C=O stretch. I: S–H stretch. J: C–H stretch.
