| 英文摘要 | the h-atom abstraction reaction, o(p-3) + ch4 -> oh + ch3, has been studied at a hyperthermal collision energy of 64 kcal mol(-1) by two crossed-molecular-beams techniques. the oh products were detected with a rotatable mass spectrometer employing electron-impact ionization, and the ch3 products were detected with the combination of resonance-enhanced multiphoton ionization (rempi) and time-sliced ion velocity-map imaging. the oh products are mainly formed through a stripping mechanism, in which the reagent o atom approaches the ch4 molecule at large impact parameters and the oh product is scattered in the forward direction: roughly the same direction as the reagent 0 atoms. most of the available energy is partitioned into product translation. the dominance of the stripping mechanism is a unique feature of such h-atom abstraction reactions at hyperthermal collision energies. in the hyperthermal reaction of o(p-3) with ch4, the h-atom abstraction reaction pathway accounts for 70% of the reactive collisions, while the h-atom elimination pathway to produce och3 + h accounts for the other 30%. |
