Extractable C6-C22 aromatic compounds from the Murchison (CM2) and Asuka-881458 (CM2) meteorites also appear to follow a systematic trend when their 5 C values are plotted against carbon number (Figure 3), although benzene and toluene from Murchison and naphthalene and biphenyl from Asuka-881458 are clear outliers. The 5 C values of many of the aromatic compounds extracted (e.g., Asuka-881458 fluoranthene —8.3%c) are markedly...
