Dynamics of reactions O((1)D)+C(6)H(6) and C(6)D(6)
The reaction between O((1)D) and C(6)H(6) (or C(6)D(6)) was investigated with crossed-molecular-beam reactive scattering and time-resolved Fourier-transform infrared spectroscopy. From the crossed-molecular-beam experiments, four product channels were identified. The major channel is the formation o...

At the earliest applicable period (0-5 mus), CO shows a rotational distribution corresponding to a temperature of approximately 1480 K for upsilon=1 and 920-700 K for upsilon=2-6, indicating possible involvement of two reaction channels; the vibrational distribution of CO corresponds to a temperature of approximately 5800 K. OH shows a rotational distribution corresponding to a temperature of approximately 650 K for upsilon=1-3 and a vibrational temperature of approximately 4830 K. The branching ratio of [CO]/[OH]=2.1+/-0.4 for O((1)D)+C(6)H(6) and [CO]/[OD]>2.9 for O((1)D)+C(6)D(6) is consistent with the expectation for an abstraction reaction. The mechanism of the reaction may be understood from considering the energetics of the intermediate species and transition states calculated at the G2M(CC5) level of theory for the O((1)D)+C(6)H(6) reaction.
