In this review, we outline the application of Raman spectroscopic measurements to high pressure researches. Raman spectroscopic measurements provides a useful means of investigating phase transformations because its spectral structure is closely related to the atomic arrangement in the crystal. Recently, Raman spectral measuring systems with high sensitivity are developed by using liquid nitrogen cooled CCD camera. Combining these Raman measuring systems with diamond anvil cell, Raman spectroscopic measurement under high pressure provides a useful means to investigate the crystal structure of unknown high pressure phase. The Raman spectroscopic studies for high pressure phases of TiO2 and ZrO2 are reviewed.
