The UV/VIS spectroscopic behaviour of 7H-indolo[1,2-a]quinolinium per chlorates and their precursors, i.e. 1-phenyl-2-[2-(3-X-5-methoxy-4-hydroxy phenyl)ethenyl]- 3,3- di-methyl-3H-indolium derivatives (X = Br, Cl, NO2) in binary solvent mixtures is described. Based on the solvation equilibrium constants determined using the SA-SAB-SB model, a discussion of an influence of a band-shape parameter c and a parameter for non-specific solute/solvent interactions b on the results obtained is presented. The evaluated real equilibrium solvation constants allow to describe properly the preference of solvation
