The success rate of discovering new polymorphs by crystallization from solution may be increased if solvents with diverse properties are used during initial polymorph screening. In this study, eight solvent parameters, including hydrogen bond acceptor propensity, hydrogen bond donor propensity, polarity/dipolarity, dipole moment, dielectric constant ...

Solvent smectic order parameters from solute nematic order parameters
The Journal of Chemical Physics, 2008In 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.

Shellac-solvent interaction parameter
Polymer, 1982Abstract 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
