Diacetylene and cyanoacetylene are the largest hydrocarbon and nitrile yet identified on Titan. Investigations in the ultraviolet photochemistry of these two molecules indicates they react out of a metastable state. In previous experiments with diacetylene this group has identified benzene and phenylacetylene as initial products of the diacetylene plus butadiene reaction. In similar experiments with cyanoacetylene this group will present data which indicates the formation of cyanobenzene and phenylacetylene. These reactions are important in developing a further understanding of the chemical processes which may lead to the formation of the visible absorbing haze on Titan.
