Ir Spectrometric Studies of Ccl4 and Ar Gas Mixtures.

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 (CCl 4  + Ar) as: (10%-90%; 5%-95%; 1%-99%) and after sublimation of the argon matrix. For the (CCl 4  + 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 CCl 4 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.
