An interesting question is whether a scaling of the VA, CM and H barrier functions can map them onto INV. We have used the following linear scaling...

The model Hamiltonians are designed to mimic the lowest energy triplet and singlet potential surfaces for O + H2 along the minimum energy path of the triplet. As described by HS, the triplet state (l A ) has a collinear reaction path (l n symmetry) that correlates with 0( P)+H2 and OH( II)+H for reactant and product configurations, and with a linear 0-H-H barrier (no wells) between these...
