Solvatochromism, Linear Solvation Energy Relationships, and Chromatography

Microchemical Journal, 1993
Abstract This work is a review of the phenomenon of solvatochromism, describing in particular its origin in electronic spectroscopy. The physical basis for the Kamlet-Taft π* scale of solvent strength is reviewed and the contributions of solvent dipolarity and polarizability to this empirical scale are emphasized.

A New Linear Solvation Energy Relationship for the Solubility of Liquids in Water

Journal of Pharmaceutical Sciences, 1996
From a comparison between the linear solvation energy relationship (LSER) and the extended solubility parameter model, it has been found that the solute-solute interaction energy term is missing in the LSER equation. A new LSER equation with the supplementary interaction energy term has been proposed for the solvation process.

Partitioning properties of linear and branched ethers: Determination of linear solvation energy relationship (LSER) descriptors

Fluid Phase Equilibria, 2006
Abstract Solute descriptors of linear solvation energy relationship (LSER) for dialkyl ethers were examined as a means for improving predictions of their fate and behavior in the environment. LSER solute descriptors consist of the excess molar refraction, the polarizability/dipolarity parameter, the effective hydrogen (H)-bond acidity/basicity ...

Analysis of solvation in ionic liquids using a new linear solvation energy relationship

Journal of Chemical Technology & Biotechnology, 2004
AbstractA new linear solvation energy relationship (LSER) equation, where the solute internal energy term has been incorporated into the traditional LSER equation, is used for the analysis of solvation in ionic liquids. Modeling results obtained using the new LSER equation indicate that all solute parameters (dispersion, polarity, hydrogen bonding ...

Linear solvation energy relationship to predict the adsorption of aromatic contaminants on graphene oxide

Chemosphere, 2017
In this study, adsorption capability of aromatic contaminants on graphene oxide (GO) was predicted using linear solvation energy relationship (LSER) model for the first time. Adsorption data of 44 aromatic compounds collected from literature and our experimental results were used to establish LSER models with multiple linear regression.

Use of Fluorescence Probes for Characterization of Solvation Properties of Micelles:  A Linear Solvation Energy Relationship Study

The Journal of Physical Chemistry B, 2004
Analysis involving the linear solvation energy relationship (LSER) of the energy of maximum fluorescence of seven structurally related probes in a micellar medium has been made to obtain solvation properties of the aqueous micellar phase. Solvation interactions as expressed by the empirical Kamlet−Taft solvatochromic parameters representing dipolarity ...

Using the theoretical linear energy solvation energy relationship to correlate and predict nasal pungency thresholds

Journal of Molecular Graphics and Modelling, 2002
The theoretical linear solvation energy relationship (TLSER) has been used to correlate and characterize 44 nasal pungency threshold (NPT) values in man with parameters derived from semi-empirical molecular orbital theory. The resulting relationship provides good correlative (R2 > 0.92) and predictive (R2cy > 0.88) capability.

Modelling of partition constants: linear solvation energy relationships or PLS regression?

Journal of Chemometrics, 2009
AbstractEstimation methods for partition constants are needed in many fields of engineering and science. The partitioning between phases is determined by the free energy of the transfer and all estimation methods must therefore describe the same entity.

Linear solvation energy relationships. Solvent effects on the fluorescence of thiabendazole homologues

Chemical Physics Letters, 1982
Abstract The solvatochromic equations describing the effects of solvent polarity/polarizability (π*), solvent hydrogen bond donor acidity (α), and solvent hydrogen bond acceptor basicity (β) have been determined for several thiabendazole homologues.

Linear solvation energy relationships: "rule of thumb" for estimation of variable values

Environmental Science & Technology, 1991
For the linear solvation energy relationship (LSER), values are listed for each of the variables (V{sub i}/100, {pi}{sup *}, {beta}{sub m}, {alpha}{sub m}) for fundamental organic structures and functional groups. The authors give the guidelines to estimate LSER variable values quickly for a vast array of possible organic compounds such as those found ...
