摘要

Figure 2. Optimized geometries of some important species. from which H20 migrates with little or no barrier 75b to give the product 4. Because of the symmetry of the system, the reverse sequence, 4-7-6-5-4, namely H20 migration followed by the CH3 transfer (not shown in Figure 1 for clarity) is of course equally feasible. The simultaneous path leads directly to the symmetric transition state 8. The energy difference between the two barriers ...
