Adsorption of TOAQ on the surface of porous (silica gel) and non-porous (aerosil) silica modification does not cause rupture of intramolecular hydrogen bonds (IMHB). The fine structure spectra of TOAQ fluorescence on silica gel contain a set of frequencies that are characteristic of weakly perturbed molecules. A number of new spectral effects appear due to the existence of pores and centres of a nonhydroxyl character. Hydroxyl groups of aerosil take part in formation of intermolecular hydrogen bonding with the TOAQ C=O group. The bond energy of the four OH-groups of the TOAQ molecule changes non-uniformly, and the symmetry of an equilibrium nuclear configuration of TOAQ decreases.
