Abstract
The effect of isotropic pressure on the frequency of the fundamental Raman mode of diamond has been measured up to 40 GPa. The mode frequency increases linearly with the change in wavelength of the luminescence of ruby, which is used for pressure measurement. The mode frequency has been calculated theoretically for pressures up to 600 GPa and is found to vary sublinearly with pressure. The possibility of using the Raman mode as a pressure gauge is discussed.
