Scientific paper

The hypothesis that polycyclic aromatic hydrocarbons (PAH) are a constituent of the interstellar medium, and a source of the infrared emission bands at 3.3, 6.2, 7.7, 8.6, and 11.3 μ is being studied using PAH containing acid insoluble residue of the Orgueil CI meteorite and coal tar. FTIR spectra of Orgueil PAH material that has undergone thermal to hydrogen plasma are presented. Comparison of the laboratory measurements with observations appears to support the interstellar PAH hypothesis, and demonstrates the process of dehydrogenetation expected to take place in the interstellar medium.
