lations presented earlier. In comparison to the results in Table VIII, the multireferencc calculation of Sloan et al.13 orders the states slightly differently: 3rI, %, 'A, In. Further the RMOS fitted surface yields a 3rI-lA separation at the anion geometry of only 0.63 eV. Apparently, all four surfaces should be considered before assigning all of the experimental spectrum's features. In addition, the inclusion of the spin-orbit interaction will result in even more potential energy surfaces to be considered. Summary We have shown that the photoelectron experiment successfully probes the transition state of an asymmetric triatomic hydrogen abstraction reaction, namely, the F + OH reaction. The nature
