| 概 要 |
Here, we present several cases of photodissociation dynamics, where the conical intersection plays an important role along the overall reaction pathway. For reactions on electronically excited states, where transitions occur between adiabatic surfaces, nonadiabatic transitions are essential. The conical intersection where two different adiabatic surfaces touch has been widely accepted as the dynamic funnel for efficient nonadiabatic transitions, and yet the direct experimental probing of the conical intersection has been rare. Here, we investigate the photodissociation of thioansiole and thiophenol, and observe the interesting dependence of the reaction products on the photoexcitation energy in terms of the product branching ratio and energy partitioning. This results from the unique dynamic process occurring near the conical intersection. |
