Supercritical carbon dioxide (sc-C02) is an excellent green solvent, but its properties are not thoroughly understood. For example, fluorinated compounds have higher than expected solubility in sc-C02. Microwave spectroscopy is one way to learn more about sc-C02 because it can be used to determine detailed structures of small clusters of molecules. The purpose of this investigation was to study weak hydrogen bonding interactions in complexes of fluorinated ethylene (solute) with carbon dioxide (C02, solvent). Investigations on dimers with one C02 molecule and fluorinated ethylene were carried out previously and found two different …

Supercritical carbon dioxide (sc-C02) is a highly utilized industrial substance identified as an excellent solvent and a surfactant, which is cheaper and less hazardous than other typical solvents. The higher solubility of fluorinated hydrocarbons than their hydrocarbon (HC) analogs is not well understood and the theory behind the microsolvation of sc-C02 cannot be fully explained with the existing chemical information. Microwave spectroscopy is a good method of identifying the structural arrangement of clusters made from fluorinated HCs and C02. I n this project, microwave scans of the four different mixtures of 1 , 1-difluoroethene (DFE) …
