Insight Into

The nonadiabatic transition state theory provides insight into the T1 → S0 intersystem crossing in thiophosgene driven by quantum tunneling through the barrier formed by the crossing T1 and S0 electronic states.

Potential Applicability

On the basis of the generalized nonadiabatic transition state theory recently introduced to remedy the crucial deficiencies of the conventional transition state theory, we have presented a new formula for electron transfer rate, which can cover the whole range from adiabatic to nonadiabatic regime in the absence of solvent dynamics control. The rate is expressed as a product of the well-known Marcus theory and a new coefficient that represents the effects of nonadiabatic transition at the crossing seam surface. The numerical comparisons are performed with different approaches and the present approach shows an excellent agreement with the quantum mechanical numerical solutions from weak to strong electronic coupling. The explanation of the experimental data of Nelsen et al. manifests the potential applicability of the present theory.
