| Abstract: | Summary The possibility of evaluation of the parameters representing the dispersive solute-solvent interactions is presented. BN and Bs values can be used to describe the liquid phase polarity and to predict the retention indices of alcohols when the model
polyxyethylene glycol dialkyl ethers and their sulphur analogs are used as stationary phases. The possibility of the first
ionization potentials estimation is also presented. |
