Two component model of orientationally ordered wall adjacent liquid layers

Electronic-vibrational absorption spectra of anisole in isotropic bulk liquid phase and in orientationally ordered wall adjacent layers formed on quartz surface were measured. The spectra were registered at room (∼20 °C) temperature. The series of spectra measured for different thickness of the liquid interlayer and normalized by area manifests the existence of isobestic points. It determines the presence of different types of absorption centers there. Statistical analysis of obtained spectra shows that the number of these centers is equal to two; one of them is conditioned by a monomer and another one by the dimer. The thickness dependence of the relative concentration of monomers was investigated.
