摘要：

Duley and Jones recently proposed that small linear polyacenes (e.g., anthracene) were responsible for the IR emission observed in localized regions of some UV-excited nebulae. Linear polyacenes are relatively stable in the first excited state although they are not very stable in the ground state. This probably is the primary reason why this type of benzenoid hydrocarbons are observed in the interstellar medium. © 1990 The Chemical Society of Japan.
