Gaseous 1,3-butadiene (pressure range 600-700 Torr) gives under irradiation with cw CO2 laser (output power 18 W) products of dimerization and decomposition - 4-vinylcyclohexene, 1-butene and aromatic hydrocarbons. The observation indicates radical mechanism of the decomposition and manifests importance of the absorbed energy transfer through intermolecular collisions.
