Abstract
Infrared spectroscopy of molecular compounds represents the most relevant method for studying low-temperature objects in the solar system and beyond. The whole research area represents the study of low-temperature, amorphous and crystalline states of phases, identified in planetary scientific work. There is a useful symbiosis between the results obtained in the course of the analysis of spacecraft and model experimental installations in their terrestrial conditions. This work presents the results of the study of optical properties and methods of cryomatric isolation of CCl4. Argon Ar and nitrogen N2 (pure 99.99%) was used as the matrix gas, representing its optically transparent in the IR range of matrix gas studies. Range of optical studies 400-4200 cm-1, temperature range of cryocondensates T = 16 – 120 K. The optical characteristics of CCL4 condensates have been studied in the process of sublimation of matrix gas during thermocycling of condensate samples with condensation surface. Experimentally discovered and confirmed for cryocondensates CCl4 the existence of a stable structural state in the low temperature range. This fact can be used in the method of studying the stabilization of molecular compounds during condensation on cooled surfaces in high vacuum. As a cryomatrix in the temperature range T = 16 – 80 K can use CCl4.
