Linear solvation energy relationships Solvent effects on some fluorescence probes
Chemical Physics Letters, 1981Abstract Solvent effects on the fluorescence probes, 7-amino-4-methylcoumarin, 7-(N,N-dimethylamino)-4-methylcoumarin, and potassium 2-( p -toluidino)-6-naphthalenesulfonate are unravelled and rationalized in terms of multiple dependences on the solvatochromic parameters π * , α, and β.

Solvatochromic Linear Solvation Energy Relationships for Solubility of O2 in Various Solvents
Bulletin of the Chemical Society of Japan, 1998Abstract Linear solvation energy relationships for solution of O2 in 27 solvents have been examined. Multiple linear regression equations for mole fraction solubility of O2 are developed based on Hildebrand’s solubility parameter as well as the π*, α, and β solvatochromic parameters describing the solvent polarizability/dipolarity ...

This study investigates lipophilicity determination by chromatographic measurements using the polar embedded Ascentis RP-Amide stationary phase. As a new generation of amide-functionalized silica stationary phase, the Ascentis RP-Amide column is evaluated as a possible substitution to the n-octanol/water partitioning system for lipophilicity ...

Linear solvation energy relationships allow the prediction of a variety of solubility interactions based on a set of descriptors found in the following equation: [equation: see text]. SP refers to an intrinsic thermodynamic property that can be found experimentally for a series of solutes. Phases containing phosphate, phosphite and phosphine functional

Linear solvation energy relationships (LSERs) were used to evaluate and characterize chemical interactions that influence retention behavior in micellar liquid chromatography (MLC) and micellar electrokinetic capillary chromatography (MEKC). High correlations were found between solutes' capacity factors in MLC and in MEKC, as well as binding constants ...

Environmental Toxicology and Chemistry, 2011
Abstract Predicting the association of contaminants with both particulate and dissolved organic matter is critical in determining the fate and bioavailability of chemicals in environmental risk assessment. To date, the association of a contaminant to particulate organic matter is considered in many multimedia transport models, but the

Surface Hydrogen-Bond Components and Linear Solvation Energy Relationship Parameters
The Journal of Adhesion, 1997Abstract In 1987, van Oss, Chaudhury and Good introduced the Lewis acid (or hydrogen-bond acidic) component, γ+, and Lewis base (or hydrogen-bond basic) component, γ−, and assumed the ratio of γ+ and γ− for water at 20°C to be 1.0. With that ratio, the base components, γ−, for other liquids and polymers appeared to be overestimated.
