摘要：

The far-UV photochemistry of cyano- and dicyanoacetylene has been studied. In particular, those photolysis channels have been characterized that lead to the production of excited-state fragments and CN in the ground electronic state. Following photolysis of HC3N, in addition to direct production of CN and C2H, there is a second dissociation channel leading to C3N and H atoms. The results also show that at high laser intensity the HC3N dissociates by two-photon photolysis and that the C3N undergoes secondary photolysis. Photolysis of C4N2 produces CN and C3N radicals. © 1990 American Chemical Society.
