Comparative analysis of calculated (subject to solvent influence in PCM model) and experimental UV-visible spectra of peroxotitanate complexes in solutions at various conditions of occurrence. It has been shown that the change of complex composition, dependent on the solution pH value, leads to the change of characteristic absorption bands of UV-visible spectra in the wavelength range exceeding 320 nm. The tendency of the absorption bands in solution spectra to shift is correlated to the change of calculated spectra in accordance with the monomer complex unit. It has been suggested that the color of the complex solution in weakly acidic and neutral media is related to appearance of hydroperoxy-bonds between titanium atoms.
