On the distribution of the bulk-solvent correction parameters

Acta Crystallographica Section D Biological Crystallography, 2000
The distribution of the bulk-solvent correction parameters (B(sol), k(sol)) (as determined with an exponential scaling algorithm based on Babinet's principle) for 219 crystal structures deposited in the Protein Data Bank is presented. The distribution shows that (i) the range of values observed is far wider than the usually cited parameter range, (ii ...

Solvent effect - Classification of parameters describing influence of solvents

Collection of Czechoslovak Chemical Communications, 1983
On the basis of factor analysis of data matrices containing 35 empirical and non-empirical parameters for 85 solvents (or a limited matrix of 20 parameters for 51 solvents), an orthogonal set of parameters with normed normal distribution has been suggested which characterizes influence of the solvents on chemical processes.

Shellac-solvent interaction parameter

Polymer, 1982
Abstract The interaction parameter (μ) of hard and soft segments of shellac with respect to the best alcoholic solvents, i.e., ethyl alcohol and n-butyl alcohol have been estimated using osmotic pressure data. These values of μ have been found to resemble each other closely and are also near to the critical value ( μ c ). No segment-segment and no

Solvent smectic order parameters from solute nematic order parameters

The Journal of Chemical Physics, 2008
In liquid crystals, while the second and fourth rank orientational order parameters characterizing a nematic phase can be experimentally determined via several techniques, there is no straightforward experiment rendering the positional order parameters characterizing a smectic A phase.

Solvent effects on the NMR parameters of H2S and HCN

Journal of Computational Chemistry, 1999
A recently developed method to calculate singlet and triplet gauge-origin–independent magnetic properties of solvated molecules is applied to the study of those parameters that determine an observed nuclear magnetic resonance signal: the magnetizability, the nuclear shieldings, and the indirect spin–spin coupling constants.

Application of Solvent Parameters for Predicting Organogel Formation

AAPS PharmSciTech, 2018
Solvents, accounting the majority of the organogel system, have a tremendous impact on the characteristics of gels. To date, there is a large variety of organogel systems; relatively few have been investigated in the field of structure-solvent correlation.

Dependence of Solute Solubility Parameters on Solvent Polarity

Journal of Pharmaceutical Sciences, 1985
In nonpolar solvents a solute may self-associate through polar interactions, exposing its nonpolar surface to a solvent with a low solubility parameter, delta 1. In polar solvents a solute is solvated, presumably, by the polar groups of the solvent.
