Quantum effects in photosensitization: the case of singlet oxygen generation by thiothymines

Abstract

Photosensitization is the indirect electronic excitation of a molecule with the aid of a photosensitizer and is a bimolecular nonradiative energy transfer. In this study, we have attempted to elucidate...

Nonadiabatic Tunneling in Chemical Reactions

“…In particular, electron transfers, proton-coupled electron transfers, radiationless transitions, photodissociation, electronic absorption and emission spectroscopy, and other light–matter interactions including those in polaritonic chemistry can be studied in the same way. Large tunneling enhancements have also been predicted in photosensitization reactions, , and instanton theory is also being developed for this direction . In bridge-mediated electron transfers, there are three (or more) electronic states, and the instanton approach can be generalized straightforwardly to treat the multiple hops .…”
