The investigation of spin-orbit effect for the F( ²P) + HD reaction

The nonadiabatic reaction of F( ²P _3/2, ²P _1/2) with H ₂ and D ^29,30 ₂ on the Alexander-Stark-Werner potential energy surface, was investigated using the time-dependent quantum wave packet method. The initial state-resolved reactive integral cross sections were determined by summing the reaction probabilities over all the partial waves. The branching ratios and the energy-dependent reactivity of the excited spin-orbit state for the two possible products, were calculated using the cross sections. The results show that at high collision energy, the reactivity of the excited spin-orbit state for the two possible products is no more than 43% of reativity of the ground spin-orbit state.
