Abstract

Abstract IR-spectrometric studies of cryo-deposition processes and properties of thin films of cryo-vacuum condensates of a mixture of carbon tetrachloride and argon obtained by physical cryo-vacuum deposition at various concentrations have been carried out. The measurements were carried out in the temperature range 11 K − 100 K and the pressure of the gas phase 10− 8 Torr − 10− 4 Torr. The film thickness in all experiments performed was d = 2 µm. The vibrational spectra of CCl4 in an argon matrix were measured in the frequency range 400–4200 cm− 1 at mixture concentrations (CCl4 + Ar) as: (10%-90%; 5%-95%; 1%-99%) and after sublimation of the argon matrix. For the (CCl4 + Ar) system, thermal adsorption curves for the yield of the matrix gas (Ar) were obtained in the temperature range of 40K and 90K. The existence of cryocapture of CCl4 molecules of the substance of the Ar matrix was found. The results obtained suggest that, in low-temperature studies of self-organization processes in thin films, carbon tetrachloride can be used as a matrix.
