Nowadays natural gas hydrates attract special attention as a possible source of fossil fuel. According to various
 estimates, the reserves of hydrocarbons in hydrates exceed considerably explored reserves of natural gas.
 Due to the clathrate structure the unit volume of the gas hydrate can contain up to 160–180 volumes of pure gas.
 In recent years interest to a problem of gas hydrates has considerably increased. Such changes are connected
 with the progress in searches of the alternative sources of hydrocarbonic raw materials in countries that do not
 possess the resources of energy carriers. Thus gas hydrates are nonconventional sources of the hydrocarbonic
 raw materials which can be developed in the near future. At the same time, mechanisms of methane clathrate hydrates
 formations have not reached an advanced level, their thermophysical and mechanical properties have not
 been investigated profoundly. Thereby our experimental modeling of the processes of formation of methane
 clathrate hydrates in water cryomatrix prepared by co-condensation from the gas phase onto a cooled substrate
 was carried out over the range of condensation temperatures 12–60 K and pressures 10⁻⁴
 –10⁻⁶
 Torr. In our experiments
 the concentration of methane in water varied in the range of 5–90%. The thickness deposited films
 was 30–60 μm. The vibrational spectra of two-component thin films of CH₄+H₂O condensates were measured
 and analyzed
