Electron solvation in two dimensions.
نویسندگان
چکیده
Ultrafast two-photon photoemission has been used to study electron solvation at two-dimensional metal/polar-adsorbate interfaces. The molecular motion that causes the excess electron solvation is manifested as a dynamic shift in the electronic energy. Although the initially excited electron is delocalized in the plane of the interface, interactions with the adsorbate can lead to its localization. A method for determining the spatial extent of the localized electron in the plane of the interface has been developed. This spatial extent was measured to be on the order of a single adsorbate molecule.

Solvation Force of Ellipse-Shaped Molecules Moving in One Dimension and Confined between Two Parallel Planar Walls
The model fluids containing hard ellipses (HEs) and Gay-Berne (GB) particles where their center is moving in one dimension and confined between two parallel walls with different interactions are investigated using Monte Carlo simulation, NVT ensemble. The dependency of fluid pressure with respect to the wall distances is studied. The oscillatory behaviors are seen in this quantity against ...
متن کاملLinear response breakdown in solvation dynamics induced by atomic electron-transfer reactions.
The linear response (LR) approximation, which predicts identical relaxation rates from all nonequilibrium initial conditions that relax to the same equilibrium state, underlies dominant models of how solvation influences chemical reactivity. We experimentally tested the validity of LR for the solvation that accompanies partial electron transfer to and from a monatomic solute in solution. We pho...
متن کاملElectron Solvation in Neat Alcohols 6917
We have performed femtosecond studies of electron solvation in a series of neat linear alcohols. The measured formation time of the solvated electron is consistent with previous studies using solutes. The major character of electron solvation, i.e. the two-state character, is evidenced by the finding of an approximate isosbestic wavelength for methanol at 750 nm. Isotope effects for CH3OH, CH30...
متن کاملSolvent reorganization in electron and ion transfer reactions near a smooth electrified surface: a molecular dynamics study.
Molecular dynamics simulations of electron and ion transfer reactions near a smooth surface are presented, analyzing the effect of the geometrical constraint of the surface and the interfacial electric field on the relevant solvation properties of both a monovalent negative ion and a neutral atom. The simulations show that, from the solvation point of view, ion adsorption is an uphill process d...
متن کاملElectron solvation in finite systems: femtosecond dynamics of iodide. (Water)n anion clusters
Electron solvation dynamics in photoexcited anion clusters of I-(D2O)n=4-6 and I-(H2O)4-6 were probed by using femtosecond photoelectron spectroscopy (FPES). An ultrafast pump pulse excited the anion to the cluster analog of the charge-transfer-to-solvent state seen for I- in aqueous solution. Evolution of this state was monitored by time-resolved photoelectron spectroscopy using an ultrafast p...
