Tetrafluoromethane (CF4), also known as carbon tetrafluoride is a long lived greenhouse gas (PFC-14), with life time ~ 50000 years. Actually, CF4 is an anthropogenic trace gas in the atmosphere. The main sources of this gas are high technology processes, such as aluminum production, semiconductor industry, or electrical and electronic engineering. CF4 has a strong Global Warming potential due to its high lifetime in the Earth atmosphere. However, the tetrafluoride – water reaction is not well studied. CF4 is considered to be a hydrophobic gas, but we proved that it forms stable molecular complexes with the binding energy exceeding E= 3.5 kcal/mol. Due to this molecular complex, at low temperatures, CF4 molecules can be found in water or snow. We simulated the (H2O)n (n=3,4) and CF4 molecular clusters using the DFT and MP2 techniques. Some stable configurations with positive frequencies of normal vibrations have been obtained.
