A new method has been devised to observe the kinetic process of pressure-induced phase transitions proceeding rather rapidly. The transition is induced by a pressure jump in a diamond anvil cell. Raman scattering spectra of the sample are measured repeatedly during the transition. The volume fraction of a phase, with its time dependence, is evaluated from the integrated intensities of a Raman peak attributed to the phase, on an assumption of a proportional relation between the peak intensity and the volume of the corresponding phase. From a theoretical viewpoint the proportional relation is expected to hold in some cases that seem to be practical. Experimental examination for the red-to-yellow phase transition in HgI2 shows a strong support of the proportional relation, and reveals the usefulness of the new method.
