Infrared absorption spectroscopy of polycarbonate at high pressure

High-pressure Fourier-transform infrared absorption spectroscopy has been performed on polycarbonate, using a diamond anvil cell to produce pressures up to ~6 GPa. The frequencies of the vibrational modes have been measured as a function of pressure. Individual mode Grüneisen parameters have been de...

Description
Summary:High-pressure Fourier-transform infrared absorption spectroscopy has been performed on polycarbonate, using a diamond anvil cell to produce pressures up to ~6 GPa. The frequencies of the vibrational modes have been measured as a function of pressure. Individual mode Grüneisen parameters have been determined for six vibrational modes. The data were fit to models that included both volume-dependent and -independent Grüneisen parameters. The vibrational frequency shifts as a function of pressure have been found to be consistent with those measured for similar types of bonds in other molecules.
