摘要：
Absorption cross sections of terrestrial mixtures of gaseous polycyclic aromatic hydrocarbons (PAHs) have been measured in the visible to far-UV range. The spectral signatures that we have obtained are compatible with those of the extinction curve. These results support the PAH model which attributes the "unidentified" IR emission bands to these molecules. Interstellar PAHs can give an important contribution to the 2175 angstrom bump, and do absorb in the far-UV rise. We derive that they contain about 18% of the cosmic carbon.
