Electron Localization of Anions Probed by Nitrile Vibrations

Femtosecond dynamics of solvated oxygen anions. I. Bifurcated electron transfer dynamics probed by photoelectron spectroscopy

Coherent electron-lattice vibrations in trans-nanopolyacetylene probed by Raman scattering.

Unexpectedly high Raman scattering activity of carbon-carbon bond length vibrations was found in polyacetylene nanoparticles. For exciting photon energy in the transparency range of nanopolyacetylene we observed extremely high Raman scattering cross section and high intensity ratio of anti-Stokes to Stokes bands. Furthermore, the Raman activity in trans-nanopolyacetylene is characterized by int...

Dipole-bound anions of carbonyl, nitrile, and sulfoxide containing molecules

Dipole-bound anions of 27 molecules containing either a carbonyl, nitrile, or sulfoxide group were studied using Rydberg electron transfer ~RET! reactions with rubidium atoms excited to ns S and nd D excited states. The electron affinity of each molecule was obtained from the Rydberg state, nmax * , that gave the largest negative ion yield using the empirical relationship electron affinity5 23/...

Lipid-protein interactions probed by electron crystallography.

Electron crystallography is arguably the only electron cryomicroscopy (cryoEM) technique able to deliver an atomic-resolution structure of membrane proteins embedded in the lipid bilayer. In the electron crystallographic structures of the light driven ion pump, bacteriorhodopsin, and the water channel, aquaporin-0, sufficiently high resolution was obtained and both lipid and protein were visual...

Local demixion in plasticized polylactide probed by electron spin resonance.

Improving the barrier properties to gas and organic compounds of biosourced polyesters, such as polylactides (PLAs), by increasing their crystallinity has been suggested by several authors. This paper investigates the risk of microphase separation for a technological approach that would involve a plasticization of PLA, to further its crystallization kinetics, with common plasticizers: Acetyl tr...
