Abstract
The products of diacetylene's ultraviolet photochemistry over the 245–220 nm region are directly determined for the first time. At these wavelengths, the photochemistry is thought to proceed from a metastable excited state of C4H2 rather than by direct photolysis. The experimental method employs a small reaction tube attached to a pulsed nozzle. C4H2 is excited within the reaction tube where collisions of C4H* 2 with C4H2 form products which ...
