The Raman spectra of the phenothiazine crystal were measured at high pressures up to 20 kbar in a diamond-anvil cell (DAC) at several temperatures. A pressure-induced phase transition was found to occur at 2.2 kbar and 297 K. The high-pressure phase was shown to be the same as the low-temperature ferroelastic phase previously found at atmospheric pressure. The wavenumber of the fluorescence band R<SUB>1</SUB> of ruby, used as the pressure monitor in DAC, was precisely measured to obtain its temperature dependence in the temperature region where the present Raman measurements were carried out.
