Charge transfer from coherent elliptic states
We present experimental data on charge transfer from coherent elliptic states of Rydberg atoms, which are oriented relative to the impact velocity vector of monoenergetic, singly charged ions. The data cover a broad range of scaled velocities around unity, selected angles of approach over the whole sphere, all eccentricities from zero to one and principal quantum numbers ranging from n = 20 to ...
متن کاملMolecular excited states: accurate calculation of relative energies and electronic coupling between charge transfer and non-charge transfer states.
We show for a series of six small donor-acceptor dyads that the energy difference between non-charge transfer (non-CT) and charge transfer (CT) excited states, as well as the squares of the electronic couplings between these states, can be predicted from first-principles using variational orbital adapted configuration interaction singles (VOA-CIS) theory. VOA-CIS correctly predicts the observed...
متن کاملIon-induced formation of charge-transfer states in conjugated polyelectrolytes.
We use time-resolved optical spectroscopy to demonstrate that the luminescence quenching observed when ions are incorporated in films of conjugated polymers can be explained by the formation of charge-transfer (CT) states that are stabilized by the Coulomb field of ions. Our investigation is focused on a conjugated polyelectrolyte (CPE) derived from F8BT (poly(9,9'-dioctylfluorene-alt-benzothia...
متن کاملRole of charge-transfer states in bacterial photosynthesis.
Photon echo, photon-echo excitation, and "hole-burning" data recorded in the 800-990 nm region of Rhodobacter sphaeroides R26 and Rhodopseudomonas viridis reaction centers are reported. The primary process in these reaction centers, following excitation, was found to occur in approximately 25 fsec; the long-wavelength band of the primary electron donor (P) was largely homogeneously broadened. I...
متن کاملPhotoinduced charge-transfer states in subphthalocyanine-ferrocene dyads.
Very efficient stabilization of the photoinduced charge-transfer state was achieved in simple subphthalocyanine-ferrocene dyads, reaching radical pair lifetimes of about 0.2 ms.
