Photochemistry of acetylene at 1849 Angstroem

Article abstract of DOI:10.1063/1.444868

The photochemistry of acetylene at 1849 Angstroem has been studied over the pressure range from 13 to 2660 N m^-2 (0.1-20 Torr).The quantum yield of diacetylene formation has been measured as a function of C2H2 pressure and the partial pressures of He and N2.The quantum yield of H2 formation has also been obtained.It was concluded that the quantum yield for C2H2 -> C2H + H is 0.06 and that for C2H2 -> C2 + H2 is 0.1.The remaining process is the formation of a metastable acetylene which reacts either with C2H2 to form C2H radicals or is deactivated by collisionswith the walls or inert gases.The C2H radicals react 0.240+/-0.015 times as fast with C2H6 and 0.469+/-0.041 times as fast with C3H8 as with C2H2.The role of acetylene photolysis in the Titan atmosphere is briefly discussed.
