Abstract

An extensive analysis of the Raman and IR spectra of laser dyes like Coumarins and Quinones derivatives has been performed, based on a reanalysis of vibrational spectrum of Polycyclic aromatic hydrocarbons anthracene and naphthalene. Raman and FTIR techniques are used to assign the vibrational modes of Coumarin, Coumarin 480 and Coumarin 540A and 1,4 benzoquinone molecules. Vibrational modes of substituted coumarin dyes are investigated for the first time in powder form using Raman spectroscopy.
