Stereochemical effects on intervalence charge transfer
… first observation of stereochemical effects on intervalence charge transfer (IVCT) in di- and trinuclear mixed-valence complexes. The differential IVCT characteristics of the diastereoisomers of polypyridyl complexes of ruthenium and osmium offer a new and intimate probe of the fundamental …

Electrolyte Effects on the Kinetics of Comproportionation Electron-Transfer Reactions and on Intervalence Charge-Transfer Band Energies of Binuclear Ruthenium Ammine Complexes
<p>Chapter 1 describes an overview of electron-transfer reactions. The kinetic equations for ET reactions have also been described in detail.</p> <p>Chapter 2 describes a series of novel kinetic accelerations which deviate strongly from the predictions of the classical Debye-Huckle theory with a …

Metal-ligand redox interaction in the multielectron chemistry of porphyrinogen coordination compounds
… The neutral oxidation state exhibits an optical intervalence charge transfer transition, characteristic of ligand-based two-electron mixed valency (Chapter III). Dianionic zinc porphyrinogen reacts with carbon dioxide, and neutral zirconium(IV) porphyrinogen with dioxygen. Two zirconium …

Pressure Tuning of the Electronic Spectra of Quasi-One-Dimensional Mixed Valence Semiconductors
… modified to some extent, along with an intervalence charge transfer (IVCT) band characteristic of the mixed valence complex itself. The reduced salt and the oxidized salt have also been studied so that direct comparison with the monohalide could be made. For all four complexes, two first …

Synthesis, Characterization, and Mixed-Valence Studies of Conformationally Constrained Bisferrocenyl Complexes for the Study of Through-Space S***π; Interactions
… is observed in the extended sulfoxide system. No intervalence charge transfer band was observed in the truncated sulfoxide complex by monitoring the UV-Vis/NIR spectroscopy of the mixed valence complex, ruling out electronic communication. Thus, the through space electrostatic interactions of the …

Redox properties of Bis-Triarylamines and ligand properties of Thianthrenophane
… spectra in CH2Cl2 and MeCN reflects a minor charge transfer character of the electronic transitions. The UV/Vis/NIR spectra of the series of TAAs and their corresponding radical cations and the AM1 computations reveal that even small substituents may lead to strong symmetry breaking and to a …

The crystal chemistry of hibonite: an indicator for oxygen fugacity during Solar nebula condensation?
… absorption band originates from a Ti(3+)-Ti(4+) intervalence charge transfer (IVCT) transition. Such transition requires that the involved atoms occupy edge or face-sharing coordination polyhedra. This is indeed the case for Ti in hibonite which has been found, based on the structural …
