Reactive scattering of fluorine atoms and 1,3-butadiene molecules has been studied by using an improved universal cross-molecular beam device and pulsed-fluorine pulsed-atom beam generation with pulsed DC discharge. Only one dehydrogenation reaction channel was observed and was not observed Carbon single bond, carbon-carbon double bond cleavage and the formation of hydrogen fluoride molecules. The angle distribution of the reaction product and the time-of-flight mass spectrum were measured directly. By converting the experimental data from the laboratory coordinate system to the centroid coordinate system, Angle of the translational energy distribution and angle distribution of the reaction product from the three-dimensional velocity distribution of the flux diagram, concluded that the reaction of fluorine atoms and 1,3-butadiene hydrogen atoms through the formation of a long-lived intermediate body
