Fig. 9From: Rhenium solubility and speciation in aqueous fluids at high temperature and pressureComparison of spectra recorded at 700 °C of Re-bearing fluids in low-frequency range. The spectrum from each system and corresponding pressure at 700 °C are indicated on each spectrum. Raman intensities are normalized to the same Raman setup parameters (acquisition time and slit width)Back to article page
