Experimental and theoretical investigations of the O(D-1) reaction with cyclopropane
In this report, the O(D-1)+c-C3H6 reaction has been investigated using the universal crossed molecular beam technique. Angular resolved time-of-flight spectra have been measured for the observed reaction products in a single set of experiments. Four reaction channels have been observed clearly for this reaction. In addition to the OH+C3H5 channel, the two microchannels for C2H4 formation and the H-atom formation channel are also present. Different product angular distributions were measured for the observed product channels, indicating that each reaction channel occurs with distinctive dynamics. Branching ratios for all observed reaction channels have also been estimated. High-level theoretical calculations have been performed on the energetics of this reaction, indicating two major insertion pathways are likely responsible for most of the reaction channels.
