ON THE RELEVANCE OF POLYYNYL-SUBSTITUTED POLYCYCLIC AROMATIC HYDROCARBONS TO ASTROPHYSICS

We report on the absorption spectra of the polycyclic aromatic hydrocarbon (PAH) molecules anthracene, phenanthrene, and pyrene carrying either an ethynyl (-C sub(2)H) or a butadiynyl (-C sub(4)H) group. Measurements were carried out in the mid-infrared at room temperature on grains embedded in CsI...
