OPTICAL STUDIES OF H2O+C02 THIN FILMS

The choice of this type of hydrate as a study was the actual problems of cleaning the air layer of the planet from carbon. A series of experiments was carried out to record changes in vibrational spectra in a thin film of a cryocondensed mixture of water and carbon dioxide at various concentrations. The purpose of this study was to determine the presence of carbon dioxide hydrates under conditions of high vacuum and low temperature condensation from the gas phase. The interpretation of changes in the vibrational spectra depending on the sample annealing temperature and carbon dioxide concentration is given for the frequency range 2210-2260, 2270-2290, 2310-2380, 2800-3700, 3590-3610.3580-3720.3685- 3720 cm-1. When comparing the adsorption peaks of a 15% mixture of carbon dioxide with water at a condensation temperature of 15 K and further annealing of the sample.
