Structures of hydrogen-terminated linear molecules .
Structures of the three energetically lowest isomers.
TOF spectrum recorded at mass-to-charge ratio of 61 . The open circles represent the experimental data and the solid lines represent the fits. The quadrupole mass filter was set at a constant and operated them in the TOF mode to record the arrival time of the ionized products of .
Laboratory angular distributions recorded at mass-to-charge ratio of 61 . The solid circles represent the experimental data and the solid lines represent the fits utilizing the best-fit c.m. functions.
c.m. velocity contour flux map for the reaction of ground state carbon atoms (left; 0°) with diacetylene (right; 180°) forming atomic hydrogen plus the 2,4-pentadiynylidyne radical. The grey colors connect data points with an identical flux. The units of axis are given in (see legend).
Reaction mechanism of ground state carbon atoms with diacetylene molecules under single collision conditions. Relative energies are given with respect to the separated reactants in and were taken from Ref. 17. The accuracy of the energies is .
