The problem of pressure measurements in a diamond anvil cell from Raman spectra of stressed diamond anvils have been studied. A splitting of the threefold-degenerate optic mode of diamond into singlet and doublet modes was observed in the Raman spectra from the stressed anvils. On the basis of the splitting effect quantitative relations between Raman spectra from the diamond anvil tip, stresses in the anvil tip and pressure in a sample have been considered. The obtained results demonstrate that Raman spectra from the diamond anvil tip can be widely used for measurements of the normal stress in the sample (or pressure for the quasi-hydrostatic compression). The calibration of the Raman spectra against the sample pressure up to 220 GPa has been proposed. (C) 2004 American Institute of Physics.
