Abstract : Benzene photo- and radiation sensitized cis-trans isomerization of pentene-2, hexene-2, heptene-2, and octene-2 all yield the same photo- and radiostationary cis/trans ratio, viz., 1.0. Yields of benzene triplet formation and radiation-induced unsensitized isomerization of the above olefines are reported. Thin films of polybutadiene containing small amounts of certain triplet-forming organic compounds were isomerized on exposure to ultraviolet light. This demonstrates that triplet-triplet transfer from sensitizer to polymer double bonds is quite efficient in the solid state. (Author)
