✦ Synopsis

The LEPS hypersurface C of Schatz, Sokolovski and Connor, which has been devised to account for the photodetachment spectrum of the IHI -anion, is assumed in the present study of the dynamics of the I,H system. The calculation involves our previous proposed Born-Oppenheimer-type separation between the light and heavy nuclear motions. This method enables one to explain the previous photodetachment results and to provide state-to-state H-atom-exchange cross sections in low-energy IH ( v= 0 ) + I collisions. These two processes exhibit common features that are related to the topology of the electronic hypersurface.

Simple "half-collision" classical trajectories on model potential surfaces show that the lack of leaving-atom isotope effects on initial rotational state distributions P(N) in reactions of the type M\*+H2 (HD) -+MH( v, N) +H (D) would result from decomposition of H-M-H( D) intermediates on anisotrop
