This thesis contains two research projects. The first research project examined the coherent nature of electron transfer in two donor-acceptor dyads – one single acceptor control compound and one dual acceptor molecule of interest. Using transient absorption spectroscopy in the ultraviolet/visible/near-infrared and mid-infrared regions, magnetic field effect experiments, and theoretical calculations, we determined that charge recombination in the molecule of interest is electronically incoherent and spin coherent at 295 K in toluene. The second research project explored the effect of laser positioning in electron spin teleportation in a donor-acceptor-radical triad. We used pulse electron paramagnetic resonance spectroscopy and density matrix model simulations to observe the spin echo as a function of laser delay. The resulting data show damped oscillations as a function of delay, and simulations of this system agree with experimental results and provide fundamental insight into the spin dynamics of this system. Teleportation fidelity as a function of laser delay was also calculated to show oscillations also due to the phase factor between the quadrature detection channels.
