Investigation of the Synthesis and Optoelectronic Properties of Ultrasmall CdSe Quantum Dots
… 1) a multitude of defect states or 2) fluxionality, a process in which bonds between neighboring atoms are constantly being made and broken, resulting in conformational and electronic fluctuations. Determining which model most accurately describes these QDs will allow for the strategic …

Two approaches to the design and synthesis of bimetallic complexes
… without bulky substituents exhibited fluxionality in solution, which was proved by a single set of signal in 1 H NMR. In contrast, two sets of signals were observed for formamidines with bulky substituents in the ortho positions, indicating two major stereoisomers ( E and Z conformers) …

A spectroscopic study of square planar rhodium(I) complexes
… were performed at room and low temperatures. Fluxionality of the ligands (L) was observed and the exchange process was monitored by variable temperature nmr. The enthalpy and entropy values for the intermolecular exchange of L in the complexes cis-[Rh(CO)₂(X)(L)] were obtained by a complete …

Lanthanide Supramolecular Phosphate Receptors for Environmental and Medical Applications
… Then, in the second study, we investigated the fluxionality of this category of lanthanide-based receptors and found that affinity and selectivity for phosphate is due only to the metal-anion interaction and not due to any preorganization like most other supramolecular receptors. NMR and …

Study Of Covalent And Non-Covalent Interactions In Ternary Systems Involving: Metal/DNA-RNA/Protein, Where Metal = Platinum(II), Palladium(II)
… to be reversible leading to transient states and fluxionality. Both kinds of interaction are generally present in living systems, complementing the function of each other.Monofunetional Platinum-nucleobase complexes (MPNs) are synthesized via substitution of a chloride ligand by a nucleobase in …

Monte Carlo Methods for the Study of the Ro-Vibrational States of Highly Fluxional Molecules
Molecular spectroscopy remains a powerful tool for obtaining insights into fundamental chemical processes, studying the properties of reactive intermediates, and investigating the chemistry of the interstellar medium. The spectra of semi-rigid molecules are often well-described using spectroscopic …
