INTERFACIAL CHARGE SEPARATION IN PHOTORECEPTOR MEMBRANES
Photochemistry and Photobiology, 1980Abstract— A rapid change in an interfacial electric potential of isolated bovine rod outer‐segment disc membranes occurs upon illumination. This potential change, which has been detected by the use of spin labelled hydrophobic ions, apparently occurs within a low dielectric boundary region of the membrane near the external (cytoplasmic) surface and is ...

Reversible Exciplex Formation Followed Charge Separation
The Journal of Physical Chemistry A, 2008The reversible exciplex formation followed by its decomposition into an ion pair is considered, taking into account the subsequent geminate and bulk ion recombination to the triplet and singlet products (in excited and ground states). The integral kinetic equations are derived for all state populations, assuming that the spin conversion is performed by

Charge separation reactions of doubly charged benzene ions
Organic Mass Spectrometry, 1986AbstractPhotoion‐photoion coincidence spectra of benzene and benzene‐d6 photoionized by He(II) light and synchrotron radiation show the existence of six major and eight minor charge‐separation reactions of the [C6H6]2+ ion. Three main groups of ion pairs are related to [C3H3]+ + [C3H3]+, [C2H3]+ + [C4H3]+ and [CH3]+ + [C5H3]+, with appearance energies ...

Charge separation processes of highly charged fullerene ions
The Journal of Chemical Physics, 1998Using high sensitivity two sector field mass spectrometric techniques (in particular MIKE scans) we have studied quantitatively (and systematically) the energetics of the superasymmetric spontaneous decay reactions (involving either C2+ or C4+ loss) of triply, quadruply, quintuply, and sextuply charged carbon clusters ions Cnz+ in the size range from n=

Journal of the American Chemical Society, 2012
Colloidal semiconductor-metal nanoheterostructures that combine the light-harvesting ability of semiconductor nanocrystals with the catalytic activity of small metal nanoparticles show promising applications for photocatalysis, including light-driven H(2) production.

Charge Recombination versus Charge Separation in Donor−Bridge−Acceptor Systems
Journal of the American Chemical Society, 2006Optimizing the ratio of the rates for charge separation (CS) over charge recombination (CR) is crucial to create long-lived charge-separated states. Mastering the factors that govern the electron transfer (ET) rates is essential when trying to achieve molecular-scale electronics, artificial photosynthesis, and also for the further development of solar ...

Femtosecond Intramolecular Charge Separation in DCM
1996Upon photo-excitation of the laser dye molecule DCM (4-(dicyanomethylene)-2-methyl-6-(p-dimethylaminostyryl)-4-H-pyran), an intramolecular electron transfer (ET) process is known to occur. The charge separation causes an electronic polarization of the DCM molecules which in turn results in a Stokes shift of the emission band.

Charge Separation Reactions of Doubly Charged Xe Clusters
1992An experiment has been designed to investigate the double photoionization of Xe-Clusters. TEPICO and PIPICO techniques have been applied to investigate the Coulomb fragmentation of doubly charged Xe clusters. It is shown that the ionization can be described by an Auger process at higher photon energies and by a secondary ionization process at lower ...
