Abstract:

The PIs current AFOSRPECASE grant FA9950-13-1-0157, 2013-2018 has resulted in 26 publications with a direct impact on the field of electronic relaxation, especially electron and energy transfer in solution and at metal surfaces. For the case of chemical dynamics in solution, the PI has made significant strides in developing a simple and reliable surfacehopping picture for photoexcited dynamics, whereby one can model nuclear vibrations stochastically depending on the instantaneous charge state. The PI has shown that this intuitive picture of photochemistry can be justified by comparison with the quantum-classical Liouville equation, with the proviso that decoherence is correctly taken into account.
