A dual level high pressure cell using Bridgman anvils was constructed to facilitate simultaneous measurement on the samples. The anvils were of 4 mm and 5 mm diameter respectively. The anvils were made from tungsten carbide (3% cobalt binder). Pyrophyllite and steatite were used as the gasket and the pressure transmitting medium. The cell was calibrated against the polymorphic phase transition of bismuth and ytterbium.

A Jobin Yvon-Spex (HR640) monochromator with a notch filter (514·5 nm) and Ar+ ion laser has been used to set up a low cost laser Raman spectrometer. The selection and setup of the various optical components used in the present work has been solely carried out in our laboratory. The calibration of the monochromator was established from the studies of various standard mercury lines and the obtained data fitted with the reported data. Raman signals have been recorded for a number of samples e.g. diamond, ruby, carbon tetrachloride (CCI4), benzene (C6H6) and ethanol (C2H5OH). The obtained results are found to be in excellent agreement with the reported values for these materials in the literature.
