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 ...

Protection of Metals and Physical Chemistry of Surfaces, 2013
The contributions of intermolecular interactions into the molar change of free energy -ΔF of sorption on the surface of porous polymers of various natures were studied by the linear solvation-energy relationship (LSER) method. It was shown that a high correlation coefficient does not ensure reliability of the results obtained.

The separation properties of six novel stationary phases for gas chromatography, commercially available from Sigma-Aldrich (Supelco) and based on ionic liquids (ILs), were investigated. The linear solvation energy relationship model (LSER) was used to describe the molecular interactions between these stationary phases and 30 solutes. The solutes belong

Abstract In order to improve the understanding of the mechanisms involved in the adsorption of volatile organic compounds (VOCs) on coal materials, and in order to predict selectivity values between given pairs of VOCs, an LSER (Linear Solvation Energy Relationship) approach has been used.

Evaluation of column characteristics in RPLC using linear solvation energy relationships (LSERs)
Journal of Separation Science, 2003AbstractAn overview is given of our studies on the use of linear solvation energy relationships (LSERs) for evaluation and comparison of RP‐HPLC columns. From among the columns investigated, 19 columns of different types, viz. 12 narrow‐pore, 7 wide‐pore silicas containing various ligands (C18, C8, C4, CN) and obtained from 7 manufacturers, were ...

Исследованы вклады межмолекулярных взаимодействий в мольное изменение свободной энергии сорбции на поверхности пористых полимеров различной природы методом linear solvatation energy relationship (LSER). Показано, что высокий коэффициент корреляции не гарантирует достоверность получаемых результатов.
