Spectrochemical study of statistical regularities of formation of optical properties of aminophthalimide solutions in the binary solvent heptane-hexanol

Solutions of 3-amino-N-methylphthalimide and 3-(dimethylamino)-N-methylphth alimide in the binary solvent heptane-hexanol were used as examples to perf orm a spectrochemical study of statistical regularities of formation of the electronic spectra of ternary solutions. Data on the band shifts produced by first hexanol molecules entering the nearest environment of aminophthali mide molecules, and on the equilibrium constants of elementary resolvation acts were obtained, and resolvation centers were determined. The contributi ons of local and bulk interactions in formation of the optical properties o f the solutions were estimated. The resulting data were compared with the k nown data on the resolvation of the same aminophthalimides in the binary so lvent heptane-pyridine.
