Application of electron paramagnetic resonance Spectroscopy for validation of the novel (AN plus DN) solvent polarity scale
(MOLECULAR DIVERSITY PRESERVATION INT, 2008)
Based on solvation studies of polymers, the sum (1: 1) of the electron acceptor (AN) and electron donor (DN) values of solvents has been proposed as an alternative polarity scale. To test this, the electron paramagnetic ...
A THEORETICAL-STUDY OF SOLVENT A Theoretical-Study Of Solvent Effects on The Relative Thermodynamic Stabilities of The Allyl+/F- and Allyl-/Li+ Ion-Pairs in Polar Media
(Elsevier, 1990)
The relative thermodynamic stabilities of several ion-pair structures, including intimate and
solvent-separated forms, in solution have been studied for the allyl +/F- and allyl- /Li + model
systems. The electrostatic ...
A simple analysis of the influence of the solvent-induced electronic polarization on the 15N magnetic shielding of pyridine in water
(Springer, 2012-05)
Electronic polarization induced by the interaction of a reference molecule with a liquid environment is expected to affect the magnetic shielding constants.Understanding this effect using realistic theoretical models is ...
Enhancing the adsorption of CdSe quantum dots on TiO2 nanotubes by tuning the solvent polarity
(Elsevier Science, 2017-05)
The aim of this work is to report the effect of the solvent polarity on the adsorption of CdSe quantum dots (QDots) over the surface of TiO2 nanotubes and the influence of the coverage gained on the efficiency of photoanodes ...
Polarization and solvatochromic shift of ortho-betaine in water
(ELSEVIER SCIENCE BV, 2008)
Betaine dyes are known to show very large transition energy shifts in different solvents. The ortho-betaine molecule - a simple two-ring prototype of the E-T(30) Reichardt dye - has been investigated theoretically from a ...
Ketoprofen Solubility in Organic Solvents and Aqueous Co-solvent Systems: Interactions and Thermodynamic Parameters of Solvation
(Science and the Information Society, 2016-02)
Ketoprofen (KET) solubility was determined in fifteen pure solvents and aqueous-cosolvent mixtures systems. The results obtained and the parameterized values solvents allowed us to observe the influence of the latter on ...
Thermal Decomposition of Diethylketone Cyclic Triperoxide in Polar Solvents
(Csiro Publishing, 2014-02)
The thermolysis of diethylketone cyclic triperoxide (3,3,6,6,9,9-hexaethyl-1,2,4,5,7,8-hexaoxacyclononane, DEKTP) was studied in different polar solvents (ethanol, 2-propanol, 1-butanol, 2-butanol, 2-methyl-2-propanol, and ...
A simple analysis of the influence of the solvent-induced electronic polarization on the N-15 magnetic shielding of pyridine in water
(SPRINGERNEW YORK, 2012)
Electronic polarization induced by the interaction of a reference molecule with a liquid environment is expected to affect the magnetic shielding constants. Understanding this effect using realistic theoretical models is ...
SOLVENT EFFECT ON THE VALENCE TAUTOMERISM OF BENZENE OXIDE/OXEPIN MOLECULAR SYSTEM
(Sociedad Chilena de Química, 2001)
DIAGRAMAS BINARIOS SÓLIDO-LÍQUIDO MOSTRANDO LA FORMACIÓN DE COMPUESTOS EN UNA MEZCLA DE SOLVENTES POLARES
Binary liquid-solid diagram compound formation in mixtures of carbon tetrachloride-dioxane and dioxinchloroform with metastable melting-points is shown. A compound formation is observed in the mixture carbon tetra ...
