Abstract
Reactions of O(1D) with hydrocarbon monomers and clusters were investigated via a cross molecular beam experiment applying laser induced fluorescence for the detection of the OH product. The translational, vibrational, rotational, spin–orbit, and Λ-doubling state populations were analyzed. Based on this information the mechanisms for the reactions of O(1D) with methane, propane, and their clusters were established. Nonstatistical distributions are observed even for the reaction of large clusters and are discussed in terms of nonadiabatic effects induced by the long lived collision complex.
