Crossed-Molecular-Beam Study on the Formation of Phenylacetylene from Phenyl Radicals and Acetylene

摘要

During the last decades,polycyclic aromatic hydrocarbons (PAHs) and other related aromatic compounds,such as ionized PAHs,have received considerable attention from astronomers,astrobiologists,environmentalists,and the combustion community.In the interstellar medium,PAH-like species account for up to 10% of the cosmic carbon budget,have been suggested as carriers of both the unidentified infrared (UIR) emission bands and the diffuse interstellar bands (DIBs),and are also associated with the origin of life.
