https://doi.org/10.1351/goldbook.K03412
Parameters to measure separately the ability of a solvent to enter into non-specific solvent–solute interactions (@P04507@ \(\varepsilon\) and @R05240@ \(\eta _{\text{D}}\)) and specific solvent–solute interaction (solvent @B00611@ or @N04251@ \(B\) and solvent @A00079@ or @E02021@ \(E\)) as contributing to overall solvent @P04710@.
