Abstract
Confocal microscopy is a technique used in mainly in the life sciences for producing three-dimensional images of cellular structures. We have adapted the technique to measure volumes and refractive indices of fluids in a diamond anvil cell. While high-precision techniques, such as X-ray diffraction and neutron scattering, exist for measuring lattice volumes of solids, the measurement of fluid volumes is much more difficult. This new technique will allow for quick, inexpensive, and non-destructive measurements of the equation of state of fluids at high pressure. In addition, we have explored the use of carbon dioxide as a probe of the structure of fluid argon and nitrogen, using Fourier transform infrared spectroscopy. New experimental results presented here include: procedures for measuring volume and refractive index with the confocal microscope; the equation of state and refractive index of argon and water along the 300 K isotherm up to about 5 GPa; the dependence on density and pressure of the asymmetric stretching mode of carbon dioxide dissolved in argon and nitrogen at 300 K; and the IR absorption frequency of Ge:O as a function of pressure at 10 K.
