^aWithin each odor set, the odors are listed in order (odor A, B). MIX: Octanol, decanol, hexanoic acid, +carvone, methyl furoate. Values retrieved from manufacturer websites or http://pubchem.ncbi.nlm.nih.gov/. Odors were purchased from Sigma-Aldrich (propyl proprionate, hexanal, hexyl acetate, decanol, hexanoic acid, methyl 2-fuorate), Fluka (anisole, citral), Fisher Scientific (ethylbenzene), and ACROS Organics (n-amyl acetate, 2-heptanone, 2-octanone, ethyl butyrate, d-limonene, cineole, octanol, carvone). Theoretical vapor pressure (VP) is given for each odor/mixture in kPa (kilo-Pascals) and mmHg.
