Title: Raman Studies of Molecular Potential Energy Surface Changes in Supercritical Fluids
Abstract: Raman spectroscopy is used to measure changes in the vibrational potential energy surfaces of molecules in supercritical fluids. The NN, CC, and CH stretching vibrations of nitrogen, methane, and ethane are studied as a function of pressure and temperature throughout the vapor, liquid, and supercritical fluid range. The results are used to test a recently developed perturbed hard sphere fluid model. Good agreement with model predictions is found both far from the critical point and under near critical conditions.
