Abstract: Electronic absorption spectra of ten 3- and 4-substituted 3-phenyliminoxindole derivatives in solvents of different permittivity were measured and discussed. Conclusions were drawn about the nature of interactions of the studied derivatives with the medium from relationships of the slope values of linear dependences of the molar absorptivities vs. absorption band position in dependence on the logarithm of the permittivity of the medium. The electron stucture of the studied compounds was concluded from the relationships of the spectral data vs. constants expressing the electronic effects of the substituents.
