Resolving orbital pathways for intermolecular electron transfer

Intermolecular electron-transfer catalyzed on nanoparticle surfaces.

Surface-functionalized nanoparticles enhance the rate of electron transfer (ET) between Cyt c(Fe(2+)) and Co(phen)(3)(3+) by a factor of 10(5) through simultaneous electrostatic binding of an ET donor and acceptor.

Evidence for orbital-specific electron transfer to oriented haloform molecules.

Beams of hyperthermal K atoms cross beams of the oriented haloforms CF(3)H, CCl(3)H, and CBr(3)H, and transfer of an electron mainly produces K(+) and the X(-) halide ion which are detected in coincidence. As expected, the steric asymmetry of CCl(3)H and CBr(3)H is very small and the halogen end is more reactive. However, even though there are three potentially reactive centers on each molecule...

An engineered CuA Amicyanin capable of intermolecular electron transfer reactions.

The type I copper center of amicyanin was replaced with a binuclear CuA center. To create this model CuA protein, a portion of the amino acid sequence that contains three of the ligands to the native type I copper center of Paracoccus denitrificans amicyanin was replaced with the corresponding portion of sequence that provides five ligands for the CuA center of cytochrome c oxidase from P. deni...

Intermolecular electron transfer reactivity determined from cross-rate studies.

Electron-transfer cross-reactions between neutral molecules and their radical cations spanning a wide range of structural type and intrinsic reactivity have been analyzed using classical Marcus theory. The principal factor found to govern intrinsic reactivity is the inner-shell bond reorganization energy. The HOMO-LUMO overlap of alkyl groups on reacting molecules is generally sufficient to pro...
