Modeling time-coincident ultrafast electron transfer and solvation processes at molecule-semiconductor interfaces.

The Journal of chemical physics

Li L, Giokas PG, Kanai Y, Moran AM.
PMID: 24952525
J Chem Phys. 2014 Jun 21;140(23):234109. doi: 10.1063/1.4882664.

Kinetic models based on Fermi's Golden Rule are commonly employed to understand photoinduced electron transfer dynamics at molecule-semiconductor interfaces. Implicit in such second-order perturbative descriptions is the assumption that nuclear relaxation of the photoexcited electron donor is fast compared...
