The first order Raman spectrum of the layer type semiconducting compound, WSe2, has been investigated. The frequencies of the Raman active A1g, E2g1E1g, and E2g2 modes have been determined to be 253,250, 178, and 25 cm−1 respectively. Using a scaling relation the results have been compared to the values obtained previously for the isostructural compound 2H—MoS2. The good agreement that is obtained between the measured and calculated values is taken as corroboration of the present assignments in WSe2.
