Abstract

Raman spectra of CO₂ fluids were measured at 288-329 K and densities of 0.81-1.16 g/cm³. The peak area ratios of hot bands at 1265 and 1408 cm^-1 and Fermi doublet peaks at 1388 and 1285 cm ^-1 were correlated linearly with temperature. The peak area ratios are correlated with density. Calculation of the relationship between the peak area ratio, temperature, and density was achieved. Micro-Raman analysis enabled in situ temperature measurement of CO₂ fluid with high spatial resolution.
