Ultrafast coupled electron–proton transfer : The locally excited (LE) electronic state is deactivated via two sequential electron‐transfer (ET) processes at conical intersections of the LE state (blue) and the electronic ground state (black) with a charge‐transfer state (red). After each electron transfer, the proton follows the electron, thus accepting the energy deposited by the UV photon in the molecular system.
