The quenching of the O(1D) atom by CO(v=0) has been studied by means of a flash-photolytic CO-laser resonant absorption method. The complete CO vibrational population distribution (0≤v≤7) was determined at four temperatures between 246 and 323°K. The results of both isotope-labeled experiments, 16O(1D)+C18O, and simple statistical model calculations indicate that the quenching reaction takes place via a CO2 complex. The good agreement between observed and calculated CO vibrational population distributions implies that the 45.4 kcal/mole electronic energy carried by the O(1D) atom has been completely randomized among all vibrational modes of the CO2 complex.
