Empirical solvent polarity parameters E T (30) were determined by UV/VIS spectroscopy, using Dimroth-Reichardt's betaine dye, as a function of composition, for several binary solvent mixtures [i.e. polar hydrogen bond acceptor (PHBA) solvents + chloroform or dichloromethane]. Each solvent system was
