英文摘要the reaction of f with h-2 and its isotopomers is the paradigm for an exothermic triatomic abstraction reaction. in a crossed-beam scattering experiment, we determined relative integral and differential cross sections for reaction of the ground f(p-2(3/2)) and excited f*(p-2(1/2)) spin-orbit states with d-2 for collision energies of 0.25 to 1.2 kilocalorie/mole. at the lowest collision energy, f* is similar to 1.6 times more reactive than f, although reaction of f* is forbidden within the born-oppenheimer (bo) approximation. as the collision energy increases, the bo-allowed reaction rapidly dominates. we found excellent agreement between multistate, quantum reactive scattering calculations and both the measured energy dependence of the f*/f reactivity ratio and the differential cross sections. this agreement confirms the fundamental understanding of the factors controlling electronic nonadiabaticity in abstraction reactions.
