Enhancing excess electron transport in DNA.

The efficiency of excess electron transport in duplex DNA can be enhanced by limiting the pathways available for migration and using a donor of moderate strength that suppresses radical recombination through selective electron transfer to distal pyrimidines rather than proximal purines.

Ultrafast studies of excess electrons in liquid acetonitrile: revisiting the solvated electron/solvent dimer anion equilibrium.

We examine the ultrafast relaxation dynamics of excess electrons injected into liquid acetonitrile using air- and water-free techniques and compare our results to previous work on this system [Xia, C. et al. J. Chem. Phys. 2002, 117, 8855]. Excess electrons in liquid acetonitrile take on two forms: a "traditional" solvated electron that absorbs in the near-IR, and a solvated molecular dimer ani...

Excess electron localization sites in neutral water clusters.

We present approximate pseudopotential quantum-mechanical calculations of the excess electron states of equilibrated neutral water clusters sampled by classical molecular dynamics simulations. The internal energy of the clusters are representative of those present at temperatures of 200 and 300 K. Correlated electronic structure calculations are used to validate the pseudopotential for this pur...

Dynamics of Excess Electron Localization in Liquid Helium and Neon

In this paper, we address the relations between the structure, electronic level structure, energetics, and localization dynamics of an excess electron in a bubble in liquid 4He, 3He, and Ne. Our treatment of the dynamics of formation for the electron bubble rests on a quantum mechanical Wigner-Seitz description of the excess electron in conjunction with a hydrodynamic picture for the liquid. Th...
