Study of resonant charge transfer
Experimental measurements ol N₂ resonant charge transfer cross sections were performed. It was found that the energy of electrons used to produce the N₂⁺ ions is an important variable with respect to cross section. An examination of the experimental precision was performed and it was found that the …

Charge Transfer Reactions in Porous Materials
… In Chapter 3, infrared spectra of a model proton-transfer complex calculated using mixed quantum-classical molecular dynamics are calculated. These studies indicate that charge transfer dynamics and equilibria are spatially-dependent in nanoconfined systems. This is reflected in the time-dependent …

Charge transfer states in alkali metals
… revealed by both types of measurement is charge transfer from the alkali conduction band to localized orbitals bound on the impurities. The excitation spectra of halogen impurities in alkali metals have been investigated throughout the photon energy range from 5 eV to 12 eV. Threshold …

Charge-Transfer Complexes for Amine Synthesis
… to generate α-amino radicals, via a photoinduced charge-transfer complex, is reported. A multicomponent radical fragmentation-cyclization reaction was developed, combining secondary amines, cyclopropyl carboxaldehydes and alkenes, to generate cyclopentyl methylamines. To initiate the fragmentation …

The investigation of novel charge transfer systems.
… with a view to preparing a new type of charge transfer polymer system having a structure based on that of side chain liquid crystal polymers, in that the hoped for polymer was composed of charge transfer acceptors connected to a polymer backbone via a flexible alkyl spacer linkage. As …

Charge Transfer at Metal Oxide/Organic Interfaces
Interfacial charge transfer between metal oxides and organic semiconductors has been found to limit the efficiency of organic optoelectronic devices. Although a number of investigations of inorganic/organic systems exist, very few generally applicable rules for oxide/organic interfaces have been …

Structure-Function Relationships in Organic Charge-Transfer Complexes
Organic charge-transfer complexes are ordered combinations of charge-donating (D) and charge-accepting (A) compounds. The proximity of the D and A units results in a partial degree of ionicity and a band structure that is a hybrid of the parent compounds, allowing the complex to exhibit interesting …

Self-interaction and charge transfer in organic semiconductors
… photoelectron spectra, dissociation, and charge-transfer processes. In search for a solution to the self-interaction problem, a new concept for correcting commonly used density functionals for self-interaction is introduced and applied to a variety of systems, spanning small molecules, …

High oxidation state organometallics and their charge transfer materials
This research has been directed toward the systematic design and synthesis of highly oxidizing complexes. These complexes have been used as components in the molecular synthesis of solid state materials displaying cooperative electronic interactions. Complexes of the type CpVX$\sb3$ (Cp = …

Computing the energetic component of the charge-transfer symmetry factor
… ion serves as a model to investigate electron-transfer dynamics. The present classical model consists of two empirical valence bond states and a control parameter that effectively determines the reaction free energy. The model mimics an outer-sphere electron-transfer reaction that obeys Marcus …

Effect of Pressure on Intramolecular Charge-Transfer and Spin-Crossover Materials
… that exhibit an intramolecular electron transfer (IET) and (2) materials that can exist in either a high- or a low-spin electronic configuration. These materials are studied as crystalline solids, doped into polymers, and in solution. In general there are two aspects we consider: (1) in …
