We report the first scattering calculations for the F+H-2 reaction based on ab initio potential energy surfaces (PES＇s) and an exact treatment of spin-orbit and Coriolis coupling. The probability of reaction of F*(P-2(1/2)) is less than 10% of that for F(P-2(3/2)) and the overall features of the scattering are well represented by calculations on the lowest electronic PES.
