The correlations of the 0-0 transitions, the absorption and the fluorescence maxima with the (σ-Hammett constants are established for series of substituted compounds of various structures. The experimental results are analyzed in terms of the changes of the energy gaps between ground and excited states and their force constants upon substitution. On this basis, both the equally and oppositely directed shifts of the maxima of absorption and fluorescence, respectively, are understood.
